I'll admit the St. Patrick's Day comment was a bit out there. The celebration does originate from a religion, so people tend to get touchy when that happens.
Having said that, I doubt most of the people who "celebrate" that day do it the right way. Indeed, most of the time they just drink and drink until they puke their brains out. You can't say the same about X-mas because, while people do like to get drunk at X-mas parties, for the most part people do associate it with a more noble, so to speak, and religious cause.
This is why you should avoid talking about either religions or politics in such a way. Never leads to anything good. Just plain ol' trolling.
Back to topic...
-James Kirk is not as well known as James Bond. Ask any person down the street who James Bond is and they will all know. Ask them who James Kirk is and only half of them will know. Hell, I just found out his full name. Just now. The best playa's name is better known everywhere.
-James Bond doesn't think with his head, if you catch my drift. Think of the show Archer; all Archer wants to do is sleep with women. He's skilled and all but he doesn't care about that. That's a James Bond parody. James is good at what he does, but as soon as he sees a pair of shapely legs, the mission goes out the window and he ends up chasing after said girl...who does end up sleeping with him.
-Time/space travel allows Kirk to kinda step away from a relationship with a good excuse. James Bond doesn't need an excuse. He just plain leaves. So what if he awkwardly runs into a past lover? That just means he'll get to do it again with that person, because you know he will!
-Because James Bond has competition is what makes him an awesome playa. Bring it on, Brad Pitt. James would still steal Angelina from you.
-Because Kirk is kind of the leftovers. If James Bond and Kirk were after the same girl, in space or not, who do you think would win? Seriously, who would win? Kirk has no competition, so its kind of a lesser-of-evils situation.
-It doesn't matter if you're a playa in Tatooine or London. The one with the most ladies wins. In this case, James Bond.
Personally, I would have chosen Commander Sheppard as the intergalactic contestant. That would be an easy win.
