It is absurd to suggest that performing blackface could somehow liberate anyone from the tyranny of race. Race and gender are similar concepts

This is still a false equivalence. I am not arguing for gender performance, nor is gender performance the same as performing blackface. To compare these two things is to undermine the significance of imperialism and the racism that fueled it. But that's beyond the point, because this is still a straw man of my argument. I am not arguing we should continue using gender in it's current form as sex roles. I am arguing for the redefinition of man and woman as "anyone who identifies as such". I don't know how clear I need to be that this is not the same as maintaining the status quo.

Imagine implying that there is any other aspect of race.

You talk about me apparently twisting your argument, but thus far every person in this thread has done exactly this. How about taking my argument with good faith rather than immediately assuming the worst potential outcome? Your argument would be far more convincing if you didn't assume I'm acting in bad faith.

To be clear, I understand that race is a socially constructed concept. But when I said "the social aspect of race," I was most definitely implying there are other aspects of race, all equally rooted in oppression. There are economic aspects of race, there are political aspects of race.

That being said, this whole blackface/gender argument is still a straw man of my proposed redefinition of gender.

Queer theory is no different, defining "woman" as "whatever we say it is".

The difference is that instead of it being "whatever the patriarchy/men say it is," it becomes "whatever anyone says it is". It becomes a personal matter, rather than one forced upon you. Like I said before, I want ice cream and potato genders.

Women named the root of the problem long ago, without the help of queer theory, when they said that gender is sex-based oppression.

Yup and now we're still just as far from gender abolition as we have ever been so if you want I have a cool theory that redefines gender to be whatever each individual personally wants themselves to be, and frees them of being forced into a specific sex role.
