It's ridiculous to see anyone try to rationalize Trump's moronically immature attacks. It doesn't matter how partisan, stupidly liberal, and shallow Morning Joe is, or that these two hosts are typical coastal libs, it's beneath the office of President to get into these little spats, period. When people try to justify Trump's stupidity they sound like parents of a misbehaved teen, trying to cover up the objectively bad behavior in a stage of denial.  The reason it sounds that way is because Trump is basically a bratty adolescent in need of a good kick in the pants. So stop trying to rationalize or President's behavior!
