Speaking of myself I can be friends and enjoy company of any like minded person.
Others I think are indifferent and the ones that might not like crossdressers just do not understand it because they are not exposed to it. For many crossdressers are closeted and a private thing and just not out there. Most gays I known are proud and out there.
And reading here many cders are private , some ashamed and many secretive.
So generally GGs are not exposed to cders so it feels like something odd or scary.
