What precisely are you accusing them of? As a gesture of good-faith, I'll put my subtext-cards down on the metaphorical table first: I believe the quippy-looking retort is actually a dud once we open it up and look inside.

For example, is it one of these?

1. "Being a regular here necessarily means you cannot actually have that opinion, so you are lying to us."

2. "You may believe that, but posting it here is not logical because nobody here will be receptive to it."

3. "You may believe that, but posting it here is an immoral offense against the management."
