Sebastian Bach Goes After Fan

So Sebastian Bach went nuts on a fan during a recent show in Toronto. Apparently the fan bumped (or maybe pushed) into his 70 year old mom. Video of the incident is below.

So let's unpack this. 1) I don't condone Bach going ballistic on anyone, but 2) if someone was legitimately shoving my mom, I'd be pissed too and let it be known and 3), why was his mom even in the crowd? She should have just been sidestage or backstage. What do you think?
