It does (to me at least). teadrinker is obviously claiming that all of the guys defending (or just agreeing with) the blogger (Anne) are 'white knights.' You might not agree with that claim (as I don't), but it does make sense in context.

But how could they be angling for sexual favors when they are essentially anonymous, and she is a married woman with grown children? It seems like it's been taken wildly out of context, and the term is being used to attempt to mock and shame people (many of whom are straight women). I find it to be a silly stretch, at the very least.
