My conclusion is it it plain old rudeness that splits them not the difference in values. If you think Trump was kind to him, then we have nothing further to discuss. Your definition of kind is something with which I am not familiar.
I understand your reaction. A very old friend had the same reaction. So many in the MSM relentlessly criticized him for what they categorized as his “tone”.
Yet, what they fail to see, is that it IS “kind” to expose their evil in this manner in order to successfully vanquish it.
DJT himself reveals he never makes the “first strike”. If you recall, cocky Bush mocked him when DJT first announced his candidacy. Before the first debate, Bush ran a very nasty ad, and made repeated disparaging remarks against Trump. That was beyond “rude”.
Trump hits back, and thank God he does. It was what was necessary in order to finally and successfully take down the Bush dynasty. No one or nothing else had heretofore been successful. A “kinder, gentler” tone always fails to defeat the Tyrant.
He fought fire with fire, and won.
