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?

I can read news through news outlets online which I do from time to time. I just want my lemmy to have tech related posts only. Your comment made me chuckle.
But tech IS political. Can you show me an example of non-political tech?
You signed up on one of the most political instances there is. Switch instances and browse Local. Like the other person suggested, lemmy.zip or programming.dev are both good options.
Does this mean I only see comments from the instance I set up an account with?
No, comments are federated, or else I would be almost an island by my self on my instance
Join Lemmy.zip and just browse the local comms. I believe they are tech centered.
