That’s the cycle of most new platforms. Early adopters are typically tech savvy and highly educated people, who in turn have a strong left tendency and also in general a tendency of questioning the status quo and wanting to improve and change things. It’s fundamentally incompatible with conservatism overall, left or right leaning. A big part of conservative ideology is not just the usual fiscal responsibility yada yada, it’s also resisting fast change and keeping traditions and existing lifestyles. Adopting bleeding edge platforms is bog change and trying out new things. New platforms also tend to reach the left worldwide before the right comes to it, so there will definitely also be a lot of anti-american bias before it essentially gets taken over by mostly americans. Even on Reddit you’d see people go like “Reddit is an english american site go back to your country” rhetoric that just wasn’t there 5-10 years ago.
Facebook when it came out in the late 2000s also leaned very left, before it became mainstream and right wing people started using it too. Same with Twitter, same with even the very early Internet and BBSes and forums. Right wing people are the last to adopt new platforms, after hating on them for a few years.
That said, I think Trump is a bad example in this context. He’s being charged with a third indictment, and done a lot of crime so even on Reddit and TikTok it’s a huge flood of news about it.
Would also help for the right to not be seen as evil if they stopped attacking basic human rights and their stupid pointless war on “wokeness”.
