Been browsing reddit since the start of the election. With kamalas loss I'm noticing right wing voices start to emerge. Reddit is going to transition to a right wing platform right before our eyes.
I noticed the exact same thing. So many comments either celebrating Trump or just saying that everyone is being dramatic and Trump will be fine. I've also seen a lot of comments calling reddit an "extreme left echo chamber" which is just funny
I find it difficult to defend the idea that Reddit is not a leftist echo chamber. I love Reddit, but it's not a place you go for open and honest discussions between people from both sides of the aisle. Even non-political subreddits will meet right-leaning and conservative ideas with hostility. You can browse the front page of Reddit every day and never see a single thing even remotely pro-Trump or pro-Republican. That's not a knock on Reddit. That's just the truth.
None of what you said makes it "leftist" though. In fact, I'd say you're likely to get banned from r/politics way faster attacking the DNC party-line neoliberal orthodoxy from the left than you would be from the right.
I think seeing anything protrump hit the front page would be so triggering for anyone on there they would leave or have words. This is not a political environment where these two side can exist in the same space because one side is ok with authoritarian and xenophobic rhetoric.
The closest I've ever found was a heavily moderated sub on Reddit. I have no idea if its still any good or not because I haven't been there in over a year.
