The view you are adding whatever credence being trans gives you to the discussion not only is incorrect it is adopted and propagated to back-justify oppression.
Do not do that.
A woman who was assigned female at birth and later lost her uterus to cancer wouldn't stop being referred to as "female, late 40s" when her chart is being filled out by EMTs. The distinction you are attempting to hold up is meaningless to how "sex" gets used socially and epidemiologically.
I never said that people should use Threads to join the Fediverse. I said that people who already use Threads can be more easily convinced to join this place.
How will you convince them if they can get everything the fediverse offers without leaving Threads?
I don't think letting people interact with you without leaving Meta hurts Meta, no.
Building something bad actors aren't allowed to access and telling people about it without letting Meta play middleman is how you get people off meta,not throwing open the doors to Evil.
I'm against it sounding like "Threads" i.e. as though it's something Meta owns and controls. For all I know your use came first and the thing I hate is Meta appropriating it, though.
The wrong two of those actors are dead. ☹️
It should have been Shatner, twice.
