...isn't it reasonable to assume that a 50 year old dude who swishes around in skirts and heels and calls himself Marsha is at the very least NOT straight?
No, it is not at all reasonable, especially for such an active forum member. It's called crossdressing, and all kinds of us do it - straight, bi, gay. Don't we know by now the difference between sexual preference and occasional dressup fun?
The crossdressing community is one that needs to stick together and continue to be there for each other for whatever one needs. We are always trying to improve the forum to better serve the crossdresser in all of us.
