If (G)od doesn't make mistakes, then what about people with diseases, or other birth defects.
Perhaps those born with diabetes should not seek medication to control their diabetes and suffer a slow painful death rather than live a long and fruitful life. They should instead read scripture (at age two) and see that (G)od loves them as their blood sugar drives them into an irreversible coma.
It's not a mistake when a infant is born with a club foot. That child should suffer being an invalid all their lives because it's wasn't a mistake in the first place and the relatively simple surgery that would correct it and allow that child to be an olympic runner is an abomination to (G)od. Rather they should seek comfort from the stories where Jesus healed the deformed and pray that he comes Tuesday, next week at 2:00 and schedule his healing. Jesus is a very busy deity, you see.
It is an absurd statement to say that (G)od doesn't make mistakes. We are all born as we are, and perhaps (G)od places these blessings-inside-curses on us to seek life and salvation. Our spiritual path is not for any man to see.
What they are really doing when they say these incredibly ignorant and stupid lies, is cover their own ignorance and hatred in between the covers of the bible. In their hearts they say that trans folks are icky. But instead of trying to understand why they feel like this, and perhaps learning that this is a congenital condition as defined by modern medical and psychiatric research. They take the easy path of stoking their fear into hatred and use the (B)ible to fan the flames.
* I use (G)od and (B)ible nomenclature to refer to the classic generalized, public belief of a superbeing in a white shirt and the adventures of creating a pocket universe that is in actuality only 5,000 years old, but shows all signs of being magnitudes older.
That which passeth all understanding is just that. You cannot put God/Goddess/et-al in a box. Nor use that white shirted image as an excuse to justify your hatred. Well, you can, of course, it just makes you look stupid.
