I wouldn't say it's leftist, though there's a lot of leftists here. Lemmy is more like how internet discussion boards used to be. There's a lot of people with weird opinions on things, and there's no Reddit Karma pushing people to conform to the consensus. So people are going to have weird takes on things, and there's not 1000 comments upvoted above the weird ones, so you're going to see comments like that. So reply to with you your weird opinions on those weird comments.
Welcome to the version internet that's not pre-packaged and filtered to be bland!
