> 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.

I agree. "It's not what you said, it's how you said it.".

Most stuff I downvote is because of the way it's expressed, not because of the opinion itself.
