Aaaand your lack of foresight makes both you and your gender/orientation/race look worse, and helps mean that the next time somebody tries to bring this up as a valid concern they'll be taken a bit less seriously.
It doesn't make her gender/orientation/race look worse. I've been critical of the article, but you're being ridiculous trying to blame a group for her comment and deletion. In fact, I suspect you already don't like those groups and this is just some confirmation bias on your part.
There are very valid arguments to be made about exclusionary practices. There are also a lot of people who bandy about "checking your privilege" and "cis scum" and whatnot, and hence make it very hard to take their (usually legitimate) grievances seriously.
I'm not trying to blame a group for her comment--I'm point out that the comment made her group (by her voluntary self-association) look bad.
