Because Eternal Truths Need Highlighting

From Shakesville:

Here’s the take-home message: when someone calls your gender conformity into question it is always about control. That person is trying to control you or to feel more in control hirself. I am trying to think of an exception from my experience, and I can’t come up with one. So, while it’s easy to laugh at Dr. S. and his sissy-yogurt nonsense, it’s important to remember that nobody who makes this kind of “joke” is ever really “just” joking.

Emphasis in original.  But making it the link reinforces the message.
