Don't start with the tone-policing, OP has addressed all the above questions in a reasonable manner.

Be civil. Don't say things you wouldn't say in a face-to-face conversation. Avoid gratuitous negativity.

When disagreeing, please reply to the argument instead of calling names. E.g. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."

They didn't have to include the postscript. It came off poorly. I'm not posting this to social media trying to get OP fired, but I will call out when people include contentless swipes at other peoples' legitimate posts.

I agree that the (now-flagged) post calling me out on my snark was fair, I would not have used that tone in real life.

He was replying to someone attempting to equate pedophilia and incest with homosexuality. Outright rudeness, not mere snark, is deserved.

12 years olds marrying each other is not paedophilia.

He didn't say anything about 12-year-olds marrying each other. You're assuming that's what he meant. He could have meant that, or he could have meant 12-year-olds marrying 40-year-olds.

Exactly this, and I'm disinclined to assume too much good faith in the sort of rhetoric he deployed.
