"It's a mat, with different CONCLUSIONS on it...and you JUMP to them! Eh? See?"
"That is the stupidest idea I've ever heard."
"Bad idea...very bad idea."
I'll chime in here - I don't care what anyone wears. Dude in a dress, fine. Chick in a three-piece suit, whatever. I don't believe in dichotomous gender to begin with, so why would I care what people wear?
This thread contains more fail per post than the FDA recommended daily allowance.
Well finally, a chic to jump in to this discussion!

I must confess, that if I had a son who wanted to crossdress, I'd be devastated. But not quite for the reason that you think.
I know that clothes are dictated by society and that fashions change with culture and time. A piece of garment that wraps around your waist is not inherently female. It's only female because of what the rest of society dictates, in a particular time and culture.
But I also know what it's like to be the out cast, to be the odd one out, never quite fitting in. I'd hate for my son to go through that. I'd cringe at the taunts and ridicule he'd suffer if he crossdressed. For that reason, I'd hate it if he was inclined that way.
But it's funny the way things change though. I have one interesting story. I distinctly remember when I was a kid, (Ugh! decades ago. Now, I'm revealing my age), and I was on my way home from school. I was walking through the turnstyles and there was this guy there walking through, wheeling his bicycle. I'm fairly certain that this was at a time when those lycra pants first came about for cycling. This guy was wearing a pair and a couple of school girls giggled and yelled out "nice pants" to him. Like I say, the early days of this lycra apparel for cycling.
And now, you hardly see anyone cycling without wearing them, male or female. I doubt anyone blinks an eye anymore. Why? Because it has become accepted. As I said before, this is an example of how society dictates fashion and clothing. It may be right, it may be wrong, but that's the way it is.
I'd hate to be ridiculed like that publicly. If I had a son in those days that cycled, I'd refuse to let him wear those cycling pants. If I had a son today, I'd buy him a pair myself for cycling. I honestly don't think it's worth it to "be who you are" and suffer taunts, ridicule and isolation from others. I've seen for myself the first hand effects of such, and I don't mean just crossdressing. I'm talking about people who have been a little different for whatever reason, whether they have been black sheep of their families, or had some social/personal difficulty like drugs or alcohol etc. And I've known people who've ended it all.
Tragically.
