That was me
For any GZ related YT I now disable comments from the outset. Else hate GZ comments start within minutes.. often containing obscenities.
And they are the first ones to cry "racists!" if you don't agree with their position.
MOM got raked over the coals in one gun blog. They seemed to resent him being there for the speaking engagement when it was obvious (to me) that he was taking their position. The right to defend oneself. It was like an oxymoron. They didn't want him there to bring attention to their cause yet he got invited to bring attention to their cause.
Methinks they were hoping for some nuggets about the case and didn't get it. Sour grapes make for nasty WHINES! LOL!
All in all. Very odd reaction. IMO.
