She called 50% of Trump's supporters racists, homophobes, etc. How is that not exactly what the quote is made out to be? If she had said "some of Trump's supporters" you'd be right.
The "deplorable" thing cost Clinton. The attacks on the Khan family don't seem to have cost Trump much at all.
In support of her defense of the statement: "to just be grossly generalistic, you could put half". That sounds very vague to me. She even referred to "you could put half" as "grossly generalistic".
Then in the rest of her statement she got to empathizing with the people that aren't voting because we have too many Muslims and brown people make me squeeamish.
