Why are Christians such hypocrites?

seriously, why?! they love to preach how we should worship the bible and it's rules/laws and yet Christians don't follow them most of the time! isn't there a saying in the bible saying something about "love thy neighbor" or something like that and another one saying something like "when an alien comes to your town treat them as you would want to be treated" even though this is said in the bible somewhere MANY Christians still don't follow these rules! also, they judge many people and isn't that one of the things you're not suppose to do either? a lot of Christians will say "ONLY God will judge your in-decencies" lol yeah, right! THOSE people are judging the other people! one last thing, i've seen MANY Christians girls wear all these really revealing clothing! so to ALL you Christians out there, why are you such hypocrites?
