> Trump appears to be an equal-opportunity mocker; his mocking mannerisms do not discriminate between targets on the basis of physical ability. :-)
even if that were true, it doesn't matter. If you had a fun joke you like to make imitating blowing your head off with a gun, and then one day you did it in front of some people and all the sudden someone breaks down...that person's spouse killed themselves in reality in just that way. What would a decent do? They'd say, "I'm so sorry!". That's all! they'd apologize. Even though they had no idea their "joke" was actually going to hurt someone. So even if Trump's lie that he didn't know this reporter were true, if he were decent (which he is absolutely not), he'd apologize (for real. Like, you just spilled your drink on someone at a party by accident apologize).
The "jokes" we make are not always the same depending on context. Trump knew very well (despite lying that he didnt know this reporter personally) that the reporter in question was disabled. Even if his routine was 100% the same (which it wasn't), he still reveals himself to be a vile human being to launch into that impression knowing its resemblance to this person's actual physical disability.
But IMO that's all moot because he knew damn well he was specifically imitating the guy's disability. After all, that is Trump's entire appeal. He doesn't care about so-called "PC". That's the basis by which his voters like him, why can't they just own that? Just own it. These trollish denials like the youtube video are fooling nobody except his own supporters who might have some inner doubt that what he's doing is really acceptable (which it of course is not). He mocked a disabled person, and you think he has every right to do so, which in fact, he does! mock away. Mocking is not illegal. But neither is overwhelming disapproval of someone's behavior by others. Trump supporters need to get over it.
