If all GC feminists identified as transgender that would cause a major upset within transgenderism. If you truly don't believe in gender identity (as in, you're not attached to your own), & if you believe transgender identification gives you extra privileges, then what is stopping you from identifying as transgender?
Sure, what transgenderism refers to as "gender identity" may be undetectable, indefinable & inconsequential on the surface, but clearly there is something substantive to it, otherwise non-believers would en-masse identify as trans, not just Lauren Southern, since there is literally nothing to lose & quite a lot to gain.
And pls none of this "but I don't believe in transgender identity" or "but I'd be living a lie" cop-out. Transgender identity is a lie. The strategy I outlined would expose that lie, via mass lobby.
