you know there's a whole subreddit for this exact question. go there. so people dont have to listen to this stupid bullshit question with its even stupider bullshit answers.
sub-lem? i dont care what you call it, I want you to know that this question and concept is always fucking stupid. just like you said, no one actually shares controversial opinions and no one knows how to handle the voting. biggest circlejerk question.
and if they did it'd just be the same bullshit like racism, oh so shocked that 15 teenage boys think its funny to say they hate mexicans
