In August 2011 there was a thread on this forum called:

Do Gays Hate Crossdressers?
http://www.crossdressers.com/forums/...-Crossdressers

The following was ReineD's comment. Maybe she'll have an update for us in this thread.
The conclusion I'm drawing from this thread, and also the "how are my gay CDs doing" thread, is that cis people in general, whether gay or straight, understand very little about gender variance.

Even people who experience gender variance have a hard time understanding those who experience a different type of gender variance. LOL.

There's a wide range of acceptance/tolerance among cis people, from those who embrace this in a SO or loved one like I do, to the liberal and politically correct type of acceptance that also has a "not in my backyard" caveat, to mere tolerance whether or not it is polite, to downright disdain.

It is clear though, that no matter where on the above scale a gay man's views might be, he is attracted sexually to other men and not to men who present as women even if he happens to have friends who CD.
