I hope all of you “marginalized” peoples don't think you can do anything you want or be anything you want, because you can't in this country due to its systemic racism, misogyny, bigotry, xenophobia, and white supremacy. White supremacists are literally everywhere, and they will—literally or figuratively-- hold you down and prevent you from achieving your dreams. Prevent you from being all you can be. And maybe even prevent you from using the bathroom of your choice! (Don't look at Clarence Thomas, Thomas Sowell, Michael Jordan, Barack Obama, Oprah Winfrey, Douglas Murray, RuPaul, Ellen Degeneres, Kyrsten Sinema, etc., etc., they are just flukes who somehow happened to become successful.)
But you can be any sex or gender you want to be. No one can prevent that, that is a simple fact. The science is settled. Even the omnipresent evil white supremacists can't keep you from exercising your Gaia-given right to be whatever sex and/or gender you choose to be!
Or color, race…species!
