For me it is "stupid people"
I am by far no genius and I make lots of mistskes but nowadays especially online but even offline it feels like the ammount of stupid people is getting higher.
Like just imagen you writr "I like catz" than if someone comes like "stupit dog hatter I dieslaike u becos u so stupit cant eben write "cats" corretly dumpas" ... and than like 10 other people will follow and say "yeah you can not even write stupid dog hater" even though you never said anything like that -.-V
doubt exactl this happened before but there are lots of similiar things I experienced and read
people starting a flame war about nothing and if you try to bring a valid argument the only answer you get is "learn how to write" or "you are stupid and I don't need to read that" ...
so frustrating dealing with this kind of people
