Well, what ever their reason, I believe it's important to view it with respect. I've been involved in several discussions where trans-people belittled each other for being "not real trans" or fake or fetishists... that makes no sense. Or at least it leads nowhere.
In this little community we must be expected to at least a minimum of open mindedness, hopefully. Even for the ones who are just in it for the sexual aspects.
Oh well...
