No, it really isn’t okay to encourage a blurring of gender lines.  It isn’t okay to stop calling same sex intercourse an abomination.  God doesn’t change His definitions of sin to match cultural fads.  He maintains rigid lines of right and wrong in order to intensify certain trials.  It is because God says having sex with animals is an abomination that struggling with bestiality is such a crisis.  If God hadn’t laid down these lines, we’d all be getting it on with whatever and whoever and never think twice about it.  God has set up rigid boundaries which He then causes some of us to feel intensely suffocated by.  He says getting drunk is wrong, then He wires some souls with intense cravings for alcohol.  He says dressing like the opposite gender is despicable, then He causes some men to feel like they’re really female inside and to want to “transition” into presenting themselves as women in public.  When we find God intentionally trapping us in these kinds of binds, we need to seek Him directly and ask Him to help us honor Him in the midst of our struggles.
