Yes, he he would be bigly a hypocrite, except I don't think he ever said not to call people names. Melania's against bullying, but that doesn't mean Don is!
Besides, nobody really thinks the "oh yeah, he's one too" argument has any merit, right? Sure, bring up whatever orangemanbad points of view you have, but that doesn't mean that your side suddenly has any effective campaign strategy to use against him.
My $0.02 for you is to not take what he says (or tweets) seriously, but take him seriously. If you could get past the blind hatred, then you could talk specifics with people like me, who don't like everything he's done. But you guys are so busy hating him, and everything he does, even if it's actually good for the country, and so many on your side are so smugly certain in the rightness of what you think about him being orangemanbad, that you've ignored the fact that he's racked up win after win for the country, AND the effect it's having on voters. They love it, and your side just can't stand it.
