There's a difference between facts and conjecture designed to create plausible deniability. I watched that whole video, and I didn't buy into the several assumptions that a person would have to believe to it's core argument. For example one point was that Trump said he didn't remember the reporter so he couldn't possibly be mocking him, but to present that as support for the argument, you'd have to make the assumption that Trump always tells the truth which is demonstrably false. What we have is a video of Trump doing sort of an impression of the reporter. I think impression is fair to say because he also throws his voice. He waves his arms around and even curls his hands at some points which is how the reporter's hands appear. The simple truth is that no one except for Trump can know for certain whether he had the reporter's disability in mind while he was imitating him. At best he mocked the reporter for supposedly being indecisive and coincidentally made hand motions that looked like they were also mocking his disability, and at worst he purposefully mocked the reporter's disability along with the supposed indecisiveness. He made fun of a disabled reporter either way. The nuance is whether he made fun of only indecisiveness or that along with the disability. The former is just Trump being a jerk and the latter is Trump being cruel. I don't understand what you're saying. He did stand up for himself and released the shorter birth certificate back in 2008. Then the crazy people kept questioning that one so he released the long form certificate in 2011. The crazy people continued to question whether both of these birth certificates were fake. He's made fun of people for questioning his heritage on numerous occasions. The most famous was when he mocked Trump at the White House Correspondents' Dinner to Trump's face. https://www.whitehouse.gov/sites/default/files/rss_viewer/birth-certificate-long-form.pdf There's the evidence. He does have egg on his face for people that see the ridiculousness of his accusation. What sickens me is that if you google Obama birth certificate, there are more articles still speculating that it's fake than any other topic about it.
