Try to start curating your block list. Whenever you see a post or a community that rubs you the wrong way/you aren’t interested in block it. Try to identify key words that help you blacklist the stuff you dont want to see.

The overwhelming Lemmy biases and echo chamber ideologies can be a little grating for sure. The longer your here the better curated your feed and the more you will find/contribute to nonpolitical communities which drastically improve the experience.
