Dave,
I have been very careful never to be disparaging about different moralities, languages or planets. Never better or worse. Just different.

You say that because there are Left Wing members I should expect to be abused.
You say that they should be expected to go for personal attack, not argue their case.
In true Stalinist style they will not argue with opponents, just denounce them. "RACIST!" "LIAR!" "EXTREMIST!"

As in a show trial, they will smear and discredit you by misrepresenting your past.

You say I should not complain or defend myself.
I should meekly accept it or leave altogether.
They want my silence so they should have it.

You have just shown how nasty you people can be Dave.
Yes, Planet Left is a different place.
Yes, your morality is different. Absent actually.
