Defending a woman on the internet is a sin and must be punished. Even if she's in the right. 
No but seriously I doubt White-Knighting is an actual thing. Being a woman who has been on the internet for a long time, I've certainly never experienced it. I've had guys stand up for me sometimes, but then usually they've not spoken to me again after that- so it may have just been that they agreed with me.
I think it's kind of stupid to accuse people of White-Knighting based on little more than `you agree with a woman and I don't`.
