I guess I'm late to the game, but no, I don't think Caitlyn Jenner's transition has any effect on the public perception of crossdressers.
I think the public is more understanding and tolerant of people who transition than of people who crossdress part time. And a large part of the problem is that many (most? I dunno) part-time crossdressers are closeted and furtive.
If you yourself keep your crossdressing a secret, go to great lengths to avoid having your "stash" found, even hide it from your spouse... doesn't it seem like you yourself think there's something wrong with it? It's hypocritical for a closeted crossdresser to expect public acceptance of something something the crossdresser him or herself treats as a shameful secret.
