Of course it's not normal, but this is the first type of president like Trump. Trump has always behaved this way. He lies, name calls, acts like a child. That's his behavior and has to own it. No different then the ones lashing out have to own their behavior.
I think people are responsible for their own actions. Trump acts like a jerk, or bully, or racist, or bigot, or homophobic, or transphobic, or whatever he's branded with. It's still up to people to control themselves. Or act like adults. If they want to get in the gutter with Trump, then they're no better. Right?
Agreed, and the people making Hitler comparisons or sniping at Melania etc. are hurting their cause more than theyre helping. My point is the things that celebrities, pundits, random Internet personalities etc say are inconsequential, the POTUSs behavior isnt.
