I've never heard "body shaming is bad unless you're body shaming a body shamer".

It misses the point in that there is collateral damage for body shaming as well - if you mock trump's weight because he is a bad person, you're still implying "fat=bad" to every good fat person out there too.

So am I allowed to mock those liberals physical qualities now, since they mocked trump for mocking someone's physical qualities? If they don't want to be mocked they shouldn't do the same to others.
