It's unclear to me how or why posting a lobbyists publicly available information along with a personal opinion should be self-censored.

If you don't like what he is up to, it makes perfect sense to contact him and let him know.

He should be all for people communicating their opinions about his actions to him, he is after all a lobbyist.

The parent didn't call you a concern troll, though. They said "this is some top-level concern trolling". Criticizing behaviour is not the same thing as name calling or personal swipes.

"Concern troll: a person who disingenuously expresses concern about an issue with the intention of undermining or derailing genuine discussion."

Yep, that's name calling. It's also poisonous to the discussion. It's not "criticizing behavior" when I wasn't doing it.

More importantly, it makes for boring reading. You can see how unproductive the conversation became.

But whatever. Just have thick skin, right? We can't simply expect people to be civil.
