Stuck between a rock and a Church Place

I have been a Christian for about ten years now, I practically live at church when it isn't the fall sports season (I run cross-country my brothers play football.) Just recently though I have started to notice the slight changes in my youth group first starting with people graduationg (which is what eventually happens) and cliques starting to form. It truely breaks my heart with this because I absolutly love the people my mentor/sister is there, my amazing artistic friend is there the adults that I look up to are there, but the more I go to the youth services the moer I wish to go to a different church. 
I have a lot of choices in that area because I have a lot of friends, and many go to the many different churches around, but my biggest predicament is the friends that I have  that are Morman have asked me to go to a couple services with them and my mom is fine with it, but the church I currently attend are all very closed minded politically (meaning all of the are republicans) and religiously (meaning if you mention the word Morman, people go off on a tangent that they are all going to hell) I don't understnad why this is, I understand the evidence that my youth pastor/senoir pastor have told me and the rest of my congragation but I honestly wish to know and see for myself. 
I also keep having this question in my heart that if we as Christians are supposed to love everyone no matter what they believe in then isn't my church being hypocritical i nthe sense they are preaching condemnation? I have never asked my Morman friends to my church because they would be ignored, given dirty looks, ect. . . and that would break my heart if that would happen to any of them.
Why is it so hard for Christians not to be hypocritcal? I know that I'm not perfect but I try not to judge people before I get to know them, I don't shove and preach what I believe in to those who either don't believe at all or are morman/catholic/johava witness. There is only so much one person can do to break a divide and I don't think it's possible for me to do that alone. I wonder if it'd be wrong for me to go to church some place else or if I'd get gossiped about at my church if I left. I truely breaks my heart in this sense that at school the Morman kids put up with so much crap from the kids that call themselves "Christian" where the Mormans are polite to the constant stabs at there religion to the fights that "Christian" kids start. I'm am truely caught between and rock and a hard place.
