is it responsible to vote for a gay president when other countries may not respect him?

Yes, In fact, I would like to appoint one just to see how civil the world tries to act when they can't agree with someone's opinions. 

Trump is easily our least respect president internationally ever. Electing him was a staggeringly stupid mistake.

Remove the word gay from your sentence and read it again.

That should not be a determining factor many in the middle East would not want to see a woman president.

They didn't have a problem with Obama did they? Send a pallet full of cash to them and see how much they respect you.

No one gives a sh!t about the Mid East. They do not respect other countries' gay president or not, or even their own citizens.

Foreign nations nothing.  Right here in the US they'd run into all sorts of issues with the religious far-right.

What would be great is if they were so fantastic that Democrats and Republicans otherwise unified under them, giving the president the highest approval ratings since Washington, only for Mormons, Christians, Jews, and Muslims to be on TV complaining about how evil they are.
