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?
So your argument is that inherent differences between groups don't mean you can't cross identify, but if it's an inherited generational difference then that's different? This seems arbitrary, and like terfs could use very similar arguments about why a condition is different
It's different! Systemic racism (I know, scary word) has led to a vast gulf of inequality based on the social construct of race. As such, that social construct (Race) is more significantly enduring than other social constructs (gender).
You seem weirdly fixated on TERF's.
