Why Can't I Marry My Jewish Girlfriend(Revised)?

Everybody wants to know details. We don't even want to get married right now, it just bugs the hell out of me that her parents won't even meet me because I'm not Jewish. They aren't even religious so the whole thing seems to be some tribal nonsense. I have no plans to convert to any religion because religion is waste of my precious time, but I have no problem with any kids being raised Jewish since they will be considered jews anyway. I've asked the question a couple of times and the answer from people against it seems to be "To secure the existence of our people and a future for Jewish children" That's what i posted in the other question. All I did was take the 14 word neo-nazi oath and replaced the word "white" with Jewish. Is the irony of that lost on you, Jews? I dont mean you good reform kind that aren't hung up on that bullshit. I mean the primitive bigots who think my and my girl's happiness should take a back seat to the opinions of some oppressive old school bearded black hats, who regard women as baby factories.
