You're entitled to your personal opinions, and I'm entitled to mine. The fact that I have an opinion doesn't invalidate yours, and it doesn't give me the moral probity to sling mud at it. There are plenty of communities, opinions and interests that aren't a good fit for me but you don't see me going around and arguing that people shouldn't participate. If you want to see change, get involved. Trash-talking just provokes more trash talk.
People are allowed to have personal opinions that differ from your own. Outside opinions can reflect on issues that insular groups habitually ignore.

Pointing out potential flaws in a community isn't "trash talk". Nor is it "mid slinging".
Complaining that you don't like a community is not constructive. Being constructive requires getting involved and participating.
