It's not just the right. On the left, people say that gender is a preference rather than biology
I scrolled past the first time you posted this, but couldn't resist a second time...
There are different definitions of gender, but pretty much all of them include the fact that it's a social / cultural construct. Given that in gendered languages objects have genders but clearly aren't biologically male of female I fear you're looking at this from an unduly blinkered perspective.
Gender /= Sex
and forget why men aren't allowed to play on women's teams--because they have a _physical_ advantage that is not diminished by the emotional preferences of the athlete.
Yeah, the vocal minority definitely shot themselves in the foot on this one, and the liberal left left on open goal by not pushing back against this vocal extreme. They forgot that fairness is not viewed from one side only. However, this isn't typical of the left as a whole, just a subsection of it.
However there's clearly more to it than just fairness, at least on the right. After all, a libertarian believes in personal liberty, right? If someone wants to mutilate their body (*cough* sorry, engage in extreme cosmetic surgery) surely that's entirely their right, their prerogative. What does it matter to you?
Or they tilt the scales in favor of specific minority groups in the name of eliminating inequality.
There's no doubt in my mind that positive discrimination has gone too far, but it's difficult to balance the scales without overshooting a little bit. I'd encourage everyone to maintain a bit of perspective, rather than just take everything back off one side of them though. Historically, they most certainly were not balanced, and that legacy still creates certain disparities in opportunity.
(These are just as abhorrent to those on the right, as mistreatment of immigrants is abhorrent to those on the left.
If mistreatment of people isn't abhorrent to you, or at least to 'those on the right', then I'd suggest we have a problem. After all, "All men are born free and equal, and have certain natural, essential, and unalienable rights..."
Perhaps we could all do with remembering this, and trying to apply it in our interpersonal relations.
