I prefer using the negativity around these made up words as dark-humour/satire and not give any further attention to it whatsoever.
I'd actually call you someone that culturally appropriates then. And your specific way of doing it - most recently became popular because of a kind of popcultural phenomenon on the far right - I like to call "the rise of the pepe people". (After Pepe the frog.)
The thing is, that none of this was done naively. The far right had a tough PR problem to solve - with all different forms of racism having been pretty clearly labeled as racism for the better part of three, four generations now.
So they got inventive. Following the same sentiment of no 'insert cultural subgroup here' in my country - they suddenly wouldnt want to call themselves racist - but 'cultural nativist' (everyone should live n the country they are born in). Makes absolutely no sense (what you anti travelers now?) but on the surface level its just ambiguous enough - that it didn't trigger the "yep thats racist" threshhold in society - for maybe two years or so. Nowadays - knowing how it came to be - we would say, that yes - its racist.
Another thing they came up with is to post openly racist content - but insisting, that they are doing so as part of a hilarious satire - that people didn't really get. Because there was none. It followed the principle of 'say something horrible' then add 'just kidding' at the and, and people dont quite know how to react anymore. Thats all the magic, behind the racially charged pepe memes. Its far right propaganda, making it possible again for people to 'talk' about racially charged stereotyping that was a societal taboo for generations.
So you might not like those cults people call religions, but you seemed to have found your own one of these which you are pretty happy with. And thats also only there because someone thought it would be a wonderful way to manipulate people into tolerating stuff, they didn't tolerate for generations. (Societal taboo.)
There are a few inklings, that you do what you do - by sharing tropes (stuff other people said), and that you havent thought this through entirely. Or that you are only out there to convince people, of lets say a certain mental aptitude (everytime I say 'stupid people exist' a moderater in here insists that they have to censor it, because its not respectful to whoever I'm accusing, so I have to find ways to say it - without saying it (kind of making the bigger point here...)) -- very similar to professional spammers who only target the not quite educated - because percentage wise, they are loosing time with more intelligent folks.
Here are two of those inklings. "I'm sorry, but are you from Nigeria [country in africa], Africa, Suriname - because I would wan't to call you the N word" is not something people ask in real life. I'm sorry to tell you.
The N word is partly 'usable' (with permission) in certain black subcultures, because it has power. The word was used for centuries to denigrate an entire group of people as 'less than humans'. In concept, and in practice. So black subcultures have tried and successfully culturally appropriated it - stripping it entirely of its original meaning - and "owning" it. This is a psychological concept - where something looses (implied, social) power over you, once you make/use/do it yourself/your own. It takes the sting out of it. They took what it meant for generations, and they made something less horrible - bordering on endearment. Its used that way to 'get over it'. But as soon as anyone else in society - pronounces - 'No, no - I also only use it that way - so 'they' can get over it' - kind of doesnt work anymore, does it.
So its still taboo - for pretty much everyone - so dont try.
There is power in this taboo as well. And no it is not a problem. Not a problem even close to the original issue, that we are trying to deal with here as society.
The next inkling that you might have not thought so good is, that you say that you would just be using the word - out of a sense of satire, irony maybe. ('If people call me a racist for that, then its not my fault.')
Now - satire, and irony are concepts (emotions) that are born out of loss. And a way to deal with sadness. So - you only venture into satire - usually - if you know of a certain thing - pretty much by heart, and because of living through it - know that it is wrong, and that you cant change it. And still have to deal with it. You don't 'make just a funny a joke with satire' to be funny. And if you do - it doesnt work.
Thats usually also something you wouldnt have to follow up with 'you can call me a racist, but', because the distinction should be very clear.
So here is your easy guideline from today on - if you have to do a double take on something with 'you can call me racist, but..' with it in the latter part of a sentence, chances are - that you said something racist. That you understood that it was racist. And that you are now worried about public perception - and now are backpadling.
But the good thing is, that you caught yourself doing it, so you know what it meant, and social shunning (taboos) still work as intended.
'I only use the negativity of those words to make fun of them' thereby doesnt work - AT ALL.
You dont decide what meaning the word gay has. Or yew. Or transsexual. Or... society does. To 'make fun' of the negativity in those words - you must understand that, when you are doing that - you are stripping them of meaning.
You do that intentionally - so people start to look at certain concepts at all, or jut so they don't always associate negative thoughts with a certain word - just the same. But you never do it "just because they are negative".
Because from that sentiment alone, all the world ever needs is some sugar frosting, and some helium balloons.
People that devide the world in toxic (negative), and positive (happy) - havent quite understood how the world, societies, or language works.
When it comes to loaded terms. A good joke always is insightful, and a bad joke is one that wasnt needed.
If you want to challange certain positions of the lets say SJW community, by all means - do it. But never do it because 'they so negative'.
