Restraint shows mindfulness of the consequences of behaviour. But here on MBTIc there are no real consequences. Getting banned is hardly a year in the chokey.

Restraint offers it's own rewards, which should be obvious when you look at the alternative.

Then again, a bit of controversy, surely, is part of the game?

The question is not one of restraint or civility but of intent.

Intent to joke or intent to injure? More likely the former, given the lack of possibilities with the latter, here on the interwebs.

Civility, restraint and other such virtues may hide malice - and deep malice at that. Whereas a rude or thoughtless quip, made in haste or jest very seldom does.

Which is of course not an apology.

All the best.
