Earlier quoted context omitted.
I'm willing to sacrifice my life for my loved ones. But I haven't. Not sure how any sane person can claim that saying you're willing to do something and actually doing it aren't different things. He said he was willing to do something but then... never did it.
This is demonstrably false. He did this at least 20 times. https://www.youtube.com/watch?v=tug8PoAa7Bg
He did it before, and he did it after. Some times more quickly than other, almost always with that rambling I-don't-even-get-the-question-non-answer sort of thing that people do when they are usually making fun of politicians. But here's the problem.
In a debate, in a high-reward scenario, on national television, Chris Wallace asked if he would denounce these groups and his first response was indignation. Arguing with Wallace over whether or not he'd done it in the past. Asking which groups specifically. Telling the Proud Boys to "stand by." The problem with all of that, right or wrong, is that he could have shut everyone up by denouncing white supremacy in all its forms and all fringe groups associated with it. He could have immediately followed up with "and you know what Chris, I've already done this on these occasions" and listed out all the times he actually did it. He could have dunked on Wallace, dunked on Biden, and picked up 25k votes across the country in the process.
But instead he did exactly what you would do if you were trying to avoid actually saying the thing someone was trying to get you to say. He played right into their hands.
