Makes sense. Perfectly natural and normal. After all, in a world where you can declare yourself to be the sex you’re not, and force everyone around you to affirm your delusion under pain of being fired and/or arrested, then you certainly can declare yourself to be a dog.
Sure. The male/female thing is only one chromosome. The dog has 39 pairs of chromosomes while the human has 23 pairs. But what’s a mere 16 pairs of chromosomes got to do with it? We all know that delusion wins over science in today’s insane world.
I’m OK with them claiming to be dogs, but they have to accept the logical consequences of their delusion: they cannot have bank accounts, credit cards or jobs. They must be on a leash at all times when outside in public. They must have a human owner who always has a pooper scooper handy. They must not eat chocolate or onions. As Ronald77 noted, they must have a dog license and their shots. They will be shot when the cops arrive and the “dog” runs to greet them.
