I’ve posted an additional page to the course site menu: LGBTQIA+ Resources.
I recommend poking around the sites I’ve linked to, as they include abundant content on gender and sexuality. In general, I recommend Googling for information, but because of widespread discrimination, there’s an abundance of incorrect and transphobic information available online. For example, when I searched “trans umbrella,” I was linked to “Focus on the Family,” a homophobic site that spreads misogynistic misinformation about trans and gender-variant people. Ick.
So be careful where you look. Pay close attention to ethos (credibility) of the sites you’re looking at.
And enjoy the resources!
