The main takeaway from the NYT article is that there is a group of people in whose writings/blog comment sections/etc racists/sexists have found a home, and his is one of them. He does not address this assertion, or what the root cause may be if it is true, or if it is not true, why not. This is the whole point of 1, 3 and 4 in his statement but he does not address it.
As to the only concrete point he addresses (point 2), he does something that is dishonest. He wrote (pre-edit):
> "blurring the already rather thin line between “feminism” and “literally Voldemort“"
and then claimed it's taken out of context. I read the whole article, especially the surroundings carefully to see if there was any context as to which could change the meaning of what he wrote here, but there is none. This simply states that there is a thin line between feminism and evil. If you believe that, then don't delete it. But if you don't, don't tell the reader it's taken out of context, just admit you made a mistake in writing this, or you have changed your mind despite this was what you believed when you wrote the article.
So there are 4 points in the rebuttal, 3 of them not addressing the point at hand, and 1 point dishonest at best. I am not impressed.
