I joined Lemmy simply because I can’t take Spez (I never had an account on Reddit) and I believe the fediverse is the future.

I would argue that that is a political stance. You are choosing Free and Open Source software with federation as the baseline over proprietary social media.

It saddens me that Lemmy attracts more extreme crowds and it becomes hard to find the moderate content.

What’s extreme and what’s moderate is relative.

I want a feed that moderates not increases the panic of the political now.

Pretty much all instances moderate, in different styles and manners. Instances are like islands, they have their own culture and style. Try to find one you like best, and stick with it, or have multiple accounts if that works for you!
