There’s been a increase in political content because there has been a major political event (Dump taking office). Both conservative and progressive content creators are going to make content reacting to that. Even smaller creators I follow have been making “political” content because they are frustrated by the new administration . For example, a cooking creator I follow had a job offer rescinded by the federal hiring freeze.
As for why so many are pro MAGA, I think they have just created a lot of more content in response to feeling emboldened by the new administration. Just don’t engage, block the worst ones, and engage highly with the content you want to see.
However, we are at a critical point in American politics right now and I think it would be difficult to completely scrub your fyp of political content. Too many people are using their platforms to speak out, and rightfully so.
