It's possible, I left 4chan a long time ago. I won't pretend it was ever a great place, but at least there were moments of entertaining randomness. Damn I'm old.

But enough talk, have at you!

"Is irrelevant" and "should be irrelevant" are two different things. Fighting by saying the issues are not there—regardless of your actual opinion—has rarely, if ever, worked. It's the same as the "I don't see color" argument.

Also, why would we exclude philosophical discussion? The point is to make you think. I also don't know who this particular person is in the OP, but the question itself has no bias. Maybe this highlights our philosophical differences, but I firmly believe that understanding a system is the most crucial step to revolutionizing it.

If the question is so irrelevant, why do you even try to answer it in the same comment? Not only answering it, but also making it a fact. As if your opinion is the only one that matters and suddenly it's irrelevant when there's a different opinion.

So long as society feels it necessary to provide protections for women, the distinction has real consequences. Drawing a line anywhere is a tradeoff between inclusivity and effectiveness.

Taking the party line "high ground" stance of either conclusive self-determination or dodging the question entirely is why this question is so effective.

I don't think it is that simple.

Women are treated different that men in many societies. In my country there are multiple laws that apply different to a person if it is a woman or a man.

If we are making legislative differentiation because those words, we ought to have them well defined and understand what we are meaning and why we say that a women gets X law applied that a man gets not.

If it is irrelevant it should be, at least, legislatively irrelevant. If it's meaningful we should be clear on what we are defining by woman (or any other gender that gets particular legislation applied for all that matters).

That without talking about the social importance of being a gendered society. I don't know any single society that is not gendered. Once again, if it is irrelevant then we should aim for genderless society. If it is relevant we should know and agree on what it is to be one gender or other.

an old cake still has the same ingredients in it.

Women were little girls until they were scorned?
