Whoa, this thread certainly got interesting.
As a binary transman, frankly, I couldn't possibly care less how anyone else wants to present themselves. Did masculine-presenting lesbians make it tougher pre-everything? Not directly (and through no fault of their own), but sure. There was no part of me that enjoyed being read as a lesbian but that's just how it went down.
It's not up to me or anyone to make choices for someone else. This is where 'opinions' can easily become toxic, especially if held by a majority.
IE: "I think lesbians and gays are disgusting and shouldn't be allowed to marry or even be in relationships!"
Majority rules, laws get passed, people's lives get steamrolled because of feelings.
I can't wrap my head around how people can't just accept that not everyone is the same and just roll with it.
The clothing argument is forced to me because clothing is so subjective and heavily dependent on whatever way society happens to be leaning. Look at the eighties, for god's sake: Everyone was androgynous. Everyone had huge hair, makeup, tons of accessories and spandex. 'Men's' clothing from that era would be scoffed at now but it was once more than perfectly acceptable.
They're just clothes. It's not the butch lesbian's fault that what she likes to wear sometimes puts us in a social bind.
