Based on a lazy google search it seems he’s never commented on the issue. But, come on, first ever AnCap president, there’s no way he doesn’t at least try and do something.
Also learned from google, apparently he’s somewhat pro-gay right, but in the typical libertarian “mind your own business” way, which I guess is better than blatant bigotry 
Yeah, like I said it was a lazy google search, I saw some quotes saying he was alright with gay marriage but under a “none of my business” logic. Like most AnCap types that usually bullshit, he’s fine with the rich being bigots if they want to.
