To play devil's advocate for a moment: So, if it doesn't bother you and the behavior may only impact their children, incest/pedophilia is acceptable as well? As an aside, imo, true gender dysphoria probably exists, but is a truly extremely rare condition. This recent huge increase in the 'popularity' of being trans is a result of some changes in society. What those are, I have my suspicions, but have too little information to form an opinion.
