We're okay with transgender/queerness because we've stopped seeing the gender divide as actually meaningful. Once we stop seeing racial divides as actually meaningful, we'll be ok with transracialism too
This is a well-studied topic, and is what’s referred to as essentialism. The fundamental difference is intergenerational discrimination.
Your understanding of this topic would be helped by reading:
This article seemed extremely weak to me. Women have also experienced many of the things this article claims are unique to black people. Would transgenderism be less acceptable in a more obviously oppressive society, such as saudi arabia?
Not sure if you got to this part, but I feel like this pretty well addresses your concern. It seems like you're misinterpreting the "intergenerationality" effect here, and only understanding it to mean "oppression".
Still weak even given this; it's unclear why intergenerationality is a good reason for disallowing transracial identities as opposed to other things. If this thing suddenly and magically applied to women, would you consider transgender identities to no longer be valid?
Or rather; these conditions imply that transgender people are only okay because there isn't sufficient difference in inherited suffering between men and women.
Which tbf does line up with my original tweet
Reframed: There is 'no' inherited suffering based on gender. In contrast, there 'is' inherited suffering based on race. Therefore, they can't be compared as equivalent.
