Feeling sad I am 'the reason'. But that's ok.

It is always the same sad story. Someone learns a new name, gets trapped inside, and tries to escalate conflict. I will not call that 'open mind'.

The deeper reason is that there is no kindness — many really don't care about others who seem alien to them. They just hide that behind all kinds of names.
