Aliens in America 

While I do agree with you, you need to avoid edit warring, as you have already been warned and blocked before on WP:3RR. While I'm not going to submit you myself, because I think that 3RR should apply only to policy violations and not people correcting them, what you are reverting would probably not be considered simple vandalism, and I don't want to see you blocked. I recommend you back down, and if people insert that content into the article in the future, take it to the administrator's noticeboard, request page protection, or just add  tags to it L
