I am not someone who follows/has interest in Geo-politics. In lemmy homepage majority of posts are political. Those lemmy’s I do not expect to have political posts in them like c/technology, c/memes, c/lemmyshitposts, their top posts are related to politics. My subscribed, local, and all is full of it. Is there a way to filter them out?

It is not that deep bro 😭
Being on Lemmy, or an internet forum in general and trying to filter out politics is like going to a political rally and blocking your ears and looking away.
Even Comedian is largely political, reaction youtubers, movies, tv shows, music, paintings, every piece of entertainment has always some political aspect to it. And Lemmy especially, for denying big tech and governments privacy intrusion on our day to day life. Most Lemmy users are moderate-far left leaning, 99% of the posts I see, I can identify some political viewpoints, so it would be very hard to “filter out politics.”
But if you really want to, just find the channels you want and block them, subscribe to mostly apolitical ones.
