In cases like that, I think that's why so many people are actually turning away from God rather than turning to Him. Yes, there are some people who get so aggressive and fanatical about their religion that they practically push it onto people, which is the wrong way to go about spreading the word of the lord.
Then of course, there's the problem of the crazed far right who are always going around spouting hatred towards certain groups (especially gays), which is not what God is about at all: God loves all people, as we're supposed to love our fellow man, so when certain religious fanatics go around saying things like, "God hates homosexuals and is going send them all straight to **** to burn for all eternity," is certainly going to turn people away who are mislead to believe in order to have a relationship with God, they have to hate certain groups of people for who they are, and therefore, are not going to want anything to do with God.
Admittedly, a friend of mine is one of those kind of fire-and-brimstone far-right fanatics who is regularly condemning gays and transgendered people on Facebook, and sometimes it gets to the point that I actually want to say STFU to her.
So, yes, both sides can get a wee bit extreme when it comes to pushing their views and beliefs onto the other side, which only makes the friction and tension worse.
