How hard is it to accept that someone thinks differently than you without dropping to insults immediately?

You seem very sensitive if you think someone asking you if you are trolling and asking you if you are being serious is "an insult". If this is what gets under your skin, I shudder at the thought of what the rest of the internet feels like to you. It must be a living nightmare.

Also, where did you get the impression that trolling required the underlying opinion to be falsely held? Whoever taught you that was doing you a disservice.

Those were legitimate questions, not insults.
