people can do what they want, as long as they don't try to enforce their vision to others.
and that's the problem !
vegan I know, they require that you do effort to accept them and cook differently, but they look upon you and criticize and insult you if you dare eat differently than them, they don't accept that you don't become vegan like them because it's the enlightenment (like they saw god) and you should stop living your life your own way.
they act like a cult and religion. they want to convert everyone, and don't accept differences. We have to accept them but they don't accept other's choices?
edit: like said above, yeah, it's aggressive propaganda.
note :
French have 3 level and 3 different words :
Vegetarien [fr] -> Vegetarian [en] : not eating meat.
This one, I'm fine and I understand, each his own taste and color. I don't eat certain things too.
Vegetalien [fr] -> vegan [en] : not eating meat, nor food produced by animals like eggs or milk.
This one I understand too, though I see it a little strange for the fact that eating eggs or drinking milk does not kill any animal, but they feel like it's torture to make breeding to produce these, but until proven wrong chicken will always produce eggs even without any human intervention.
Vegan [fr] -> no word in english? : not eating meat, nor food produced by animal, nor wearing any product from animal (leather, wool, etc.), nor killing any living organisms because life is precious !
Vegan (french meaning) is stronger than the english one, and more than just "not eating meat", it goes up to "not using, wearing, touching anything produced AND derived from animals" like silk or leather or wool because it's from animals.
They also push the fact that "eating or killing living things" is wrong. but you know, vegetal are living organisms too, right? because you don't hear them cry you think it's not alive ? will you eat rock instead?
and they also are like "it's wrong to kill anything" but, things you don't see are fine, right ? stepping on insects, ants, mosquitoes, mites, bacteria and viruses, that's all right to kill them ? at which limit it isn't ?
vegan from this category are the one that make such propaganda and try to convert everyone.
Vegan is translation of Vegetalien (the second category), but french started to borrow the english word instead of using the existing one, as if it was a cult all around the world. it's like being part of something called vegan, instead of using the existing word in its own language.
it added a more signification to that movement with more ideology than just "eating" behavior.
everyone are free to do and act like they want, don't enforce others to act like you!
