"Not thriv[ing]" is not the same as being quashed. Minority opinions don't always rise to the popularity or acceptance level of majority opinions, and that's OK.

There is a difference between expressing unpopular opinions (e.g. "manifest V3 is good"), which receive an appropriate level of considered disagreement; and expressing opinions that are removed administratively.

In my experience, the former is quite common, while the latter only occurs in cases of hateful or off-topic comments. That is as it should be. No one is obligated to agree with you, and that fact should not dissuade you from expressing yourself.

I’m a fairly steadfast holder of the “I like apples walled garden, it’s my choice to be there” argument, and I think as a dissenting opinion on this forum I get a lot of flak for it. But that’s not a moderation problem, it’s the fact that my opinion is different and I have 10x the number of people disagreeing with me than agreeing with me.

> having the opinion

What I see a lot of is this:

User posts "$opinion $generalization $snark $dismissal $adhominem".

User gets down voted or flagged. User complains that downvotes are for expressing $opinion and that $opinion is not allowed on this site!

But we can all see the other things in their post that probably brought on most of the downvotes.

That's not a moderation issue. You can post that opinion, and people will disagree with it, post responses to it, and downvote it. It will not be flagged out of existence, unless it's also violating site policy in other ways.
