On the inside, I'm fiercely protective of my butch and I will stare someone down or call them out on their rudeness (if it's obvious, I miss subtle). However, there is something to be said for taking the high road and not sinking to their level.
Being calm and rational in the face of unreasonable behavior is often the best course of action. This way, they don't have the satisfaction of saying, "You see that? Those queers are all nuts!"
Now, that being said, if anybody starts a physical altercation and my butch gets knocked down for the count, I'm pretty much going out of this world like a Klingon*. Just sayin'.
(For those of you who are not geeks like me, a Klingon is a warrior race from the Star Trek universe. Their preferred method of departing the physical plane is combat).
