I think it would be absolutely ridiculous if we couldn't.
While I accept that not everyone agrees with this, to my mind the idea that gender is a performance, a presentation, not some hard coded biological fact seems to be an essential part of liberating ourselves from strict roles and enabling trans people to live their true selves fully and without prejudice.
I want to be clear that when I say gender is a performance, that doesn't mean it's fake. Gender is an expression of something deeply integral to who you are. Often something that you could not change without causing yourself severe harm. But the presentation of that integral identity is for you to decide, and that should be true for everyone.
I think every cis person has gender goals, but most of us allow the world around us to define those goals instead of defining them for ourselves. I think that's a part of why cis people act so hateful towards trans people; because a person simply throwing out the handbook and saying "Actually, this is how I want to express myself..." reminds them that they could be doing the same thing if they wanted. I think that's also why crossdressers, trans people, and men who do nothing more radical than wear nail polish often get lumped in together. All of it is violating these supposedly hard coded realities.
So, maybe I'm wrong here, maybe I'm out of line, but I think the world would be better for everyone, cis and trans, if we all recognized that we have gender goals and were comfortable talking openly about them.
