I ask, if that person is truly unpleasant have you spoken to them about how unpleasant they are?

Not to defend but how is someone to recognise a fault of their own if they're not called upon? Unless its truly terrible and they know they are doing it on purpose.

The issue we live in nowadays we are all scared how to tell each other how we feel towards and that we now safe harbour them by throwing them a label and approving that to a degree.

I'm direct and blunt, if someone is doing something in a group I call them out of it; I expect folk to do the same for me.

I may be offended but you should be offended, there's no harm in that.

Granted it's a double edged sword. You tell them; they preach to their safe haven and breathe the toxic fumes of their peers. Or they actually recognise it.
