So, being against gay marriage is so despicable that you can't even use software that is associated with organization that is run by such a vile man. But if this vile act is performed in service of being elected president of the USA, that's completely OK. Not sure I get how that works out. To me it sounds like "Did you murder this guy? - Surely, yes. - You're going to jail! - But I'm a politician, I did it to get elected! - Oh! Why didn't you tell it from the start! It's completely different then, you're free to go."
