"Religion" As Opposed to "Christianity"

When most people hear the word "Christian", they categorize Christians in with all other religious sects that "believe in God". To these people, all Christians (as well as all other "religious people") are the same, fire and brimstone, judgmental religious fanatics who damn those who don't share their same beliefs. Some religious sects might look at the world this way, but "Christians" as I know them are not like this. I am a Christian and I wouldn't dare "damn" others because I think that I'm perfect in any sense of the word. On the contrary, I sin horribly every single day, over and over again. There are many powerful people who call themselves "Christians" who I don't agree with at all. Though it isn't my right to say whether or not they are true believers, I highly doubt that they truly are. There are those fire and brimstone fanatics and they give the rest of us a bad name, so when people look at Christians they assume that they are all like the extreme, judgmental "whatever-they-ares" (I call them this because I'm not really sure what they believe).
