Why pick Christians?

Why pick Christians? Are Christians the only ones who actually push their beliefs onto others? I consider myself a Christian, but in no way am I a devote Christian. I do not believe in the bible, but think that the stories overall are more of guidelines by how to lead a life in which you are happy and are able to help others. I do think that it is “outdated” in a way. I believe in evolution and science and am not ignorant to solid, evident proof. I do hate it when “atheists” bash other religions, and they usually target Christianity. There are Muslims who die for their god and Jews who also try to spread their beliefs. I recently started going to college and have realized that there is one Christian club, but there are many more Jewish organizations, despite the fact that they are an apparent minority. This e-mail is just my expression that even though Christians DO try to push their beliefs onto others, there are other religions who do the same. And also, it’s not Christians in general. Christianity is the main trunk but the branches are the ones who have different views. I am Roman Catholic and I don’t think that we are the ones converting others even though we are still Christina. I know Mormons try to convert people but they are only one branch of Christianity. There may be different branches that do the same but as a whole, not all Christians are asshats who try to convert others.
