No one here is talking here about perversion.  If three tenths of one percent of people have a particular problem it should be looked into.  But there is no need for the 99.7 percent to have to rethink their situation.  Gender is specific, not fluid.  There are men, and there are women.  And 99.7 % are quite comfortable about that.  So let the few with issues address those issues, but the charlatans and the political opportunists should not be muddying the waters for their own financial or political gain.  As I said before, the existence of a few blind people does not diminish the value of sight, and the existence of a few people with gender dysphoria does not diminish the value of gender specificity.  We are born male or female.  It's not that complicated.  A few exceptions do not undermine the rule.
