You ignore the fact that Trump responds to any criticism personally, not just personal criticism. Criticize his policies? He’ll hit back with an insult. Fail to adequately praise him (such as failing to report on a specific poll that is good for a Trump)? He’ll hit back with an insult.
Yes, he gets a lot of personal criticism. But his childish responses are not limited to that.
Politics these days is hand-to-hand combat. If you abide by the Marquise of Canterbury rules, you are dead meat. So yes, when some one hits you with a fly swatter, you hit them with an anvil. It’s the way it’s done now because nice guys finish last.
It is way past time for someone to fight back. I do not remember anyone doing that before. GO TRUMP!
