As far as I see, Novestador seemed to want a discussion and did not recognise that the original comment was a joke/troll. Perhaps he would have turned out to be a fedorasshole if the discussion had continued somewhere but the way that played out the ladies were the ones who ended up looking bad.
Here's the thing. By now, the cliche in the SJW community is of the fedora'd gentleman who talks fancy about how he's perfectly rational and objective and everyone else is an emotional idiot... and then proceeds to make incredibly stupid arguments that completely ignore reason and/or reality. It's a stereotype, but it does happen to some extent.
And it's an incredibly destructive meme. If your side automatically pattern-matches "person who talks about a reasonable discussion" to "complete idiot who has nothing useful to say and shall be mocked", then you've more or less made actual reasonable discussion impossible. And of course they have all the auxiliary memes about how you don't need a reasonable discussion about these things because racism/sexism/etc. are obviously wrong* so what do we even have to talk about?
And then on the other side you have people looking at the SJWs and saying "man, these guys are completely against rational debate, what idiots" and so on and so forth.
*Which they are. But "racism is wrong" is only the first part of the SJW creed, and what people want to discuss is all the other, less obvious parts.
