Activists have cause and effect reversed. It's not that trannies are suicidal, it's that suicidal people become trannies because it presents a false opportunity to symbolically kill your former self (hence the Freudian slip of "deadnaming") in order to escape your problems.

Only problem is it doesn't actually solve your problems, but it adds a bunch of new problems, so when the consequences of ignoring reality can no longer be ignored, that's it.
