We'll see what his actions show in the future. Trump is not a religious man in the slightest, so this is one of the very few areas I'd give him the benefit of the doubt. Still, we know Pence is anti-LGBT. The question that arises is did Trump willingly pick Pence knowing this.
At the very least he's the first President to claim to not be anti-LGBT to get into office, as the title suggests. Exploit is a strong word given we haven't seen the practice, but I understand the sentiment.
I'm hoping for the best here, but Trump is certainly the type of president who could dismantle that hope in a moment's notice.
