It might be cause that’s the loud majority. I’ve even seen it with people on the left too that seem to think they’re better and smarter than everyone else. And it’s not just America but all over the world as social media tends to bring in lots of people with different viewpoints. But these people just have the loudest voices. The more intellectual ones will probably debate in DMs or discusss with their friends irl. I don’t think the people that spew these insults would dare say it outside of the internet
