I think my server descriptions says something similar. And I’d say I get overwhelmed by too much political content quite quickly. My home timeline (people I follow and their boosts) is fine though. If I don‘t want to read something, filter keywords, mute, unfollow, worst case block the user. It‘s my timeline and on Mastodon I can control the content in it pretty good. If I‘m up to it, I scroll through the local or federated timelines. But if I‘m not, I just don’t. I can’t control what other people post but I can control what is displayed to me.

And in the end, the general answer to not liking posts on mastodon (after the steps I wrote above) is switching instances.
