This is kind of like someone who claims to be a scientist, but is actually an alchemist or something like that. Just because an individual or a group of people claim to be something, doesn't mean that they are what they say they are. The one who defined which kind of people would actually be "Christian" should be the very person that arguably started it all: Jesus. He also said that many people would claim to be his followers, but they'd be fake and also that his original stand of Christianity would be infected by apostasy and greed.

I understand that for someone who may not believe and already has a negative view of Christian, this may be just one more reason to criticize the ideology as a whole. However, the fact that one meets several bad doctors, does not mean that medicine is flawed, it just mean that the people who claimed to be doctors, weren't doctors in the first place.

Christianity was never about preventing gay marriage, interfering on politics in any way whatsoever, trying to change bills about abortions or gun control, it was supposed to be about "love", pure and simple. Jesus washed the feet of his disciples, he didn't try to take over the Synagogue, he talked to many people about loving their families and turning the other cheek, he never told anyone to affect the political institutions. He actually said the opposite, that his true followers would not be involved with the world, in terms of political environment and social paradigm.

Finally, he said that his followers would choose a small path, narrow and difficult, and that their numbers would be very low. Christianity as a whole is a very large institution with several hundred different dogmas inside of it. It is safe to assume that not all of them, if any, constitute what he intended to be his true followers.
