'white knights' is a 4chan term. It originated on /b/ when women/girls would show post nude/revealing pictures of themselves, and then Anonymous (presumably male) posters would attempt to 'dox' them (hack their accounts; email their friends/family/school with the nude photos; etc). The 'white knights' were the guys that would defend them (e.g. warn them if they didn't know their images were on 4chan; login to a hacked account, change the password, and notify the owner so that other anonymous posters couldn't continue to 'have fun' with the account; etc). The stereotypical portrayal of internet 'white knights' are lonely geeks that can't get women who think that by defending them on the internet they might get laid (or at least a date/a kiss/etc). Obviously the stereotype is most likely far from the truth, and there's probably some overlap between what /b/ users call 'moral fags' and 'white knights.' Note, that the 'white knight' label is usually only used when someone of unknown gender (which is assumed to be male) is helping out someone that is known to be a female. I don't think the 'white knight' label would ever be applied to someone helping out a target that was known to be male.

edit: There's probably something on Know You Meme and/or Encyclopedia Dramatica about this that may (or may not) be more authoritative.

Thanks for the write up! The less time I spend looking at anything on ED, the better... I have heard this term before, but it always leaves me scratching my head. It makes no sense in the context of this disagreement.

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.
