I heard some whoppers:
:galaxy-brain: "I have studied every religion. They are all parts of the same universal truth... except Boodyhizzim." (yes he pronounced Buddhism as Boodyhizzim.)
:wojak-nooo: "I am so sick of poor people dominating gaming. Developers are forced to make weaker games with worse graphics because the poor need to be catered do. My rig is top of the line and nothing uses its full potential."
:frothingfash: "Being gay is a choice. Gay men aren't just d---------s, they're lazy because men always want to get laid and it's easier to fuck men."
I one time, in front of a guy doing the whole "ezy welfare queen" thing, pulled up the florida state website on welfare and showed him it was like 50 bucks and fruit basket aside from food stamps, and he still refused to believe me. Like I dared him to try and find/apply for more and he would just refuse and dig in his heels that "unmarried mothers" were getting like 50K a year.
