I'd like to point out that despite the unfortunate set of circumstances presented to us by the OP, hating, disliking and not understanding transgender people is not a problem with religion solely but with social norms and society itself, all kinds of people criticize and mocks trans, from catholics, muslims to pro-gay marriage people who think transgenderism is not natural and not the same as being gay (it's not obviously but it still doesn't excuse the bashing)
Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
