You're taking things out of context, which doesn't represent Christianity as a whole, but just a select few. They don't hate us, they just try to convert us because it's one of the major parts of Christianity.
And you're showing a video of an "extremist" group of Christians. You had to have seen the whole movie, and not just two minutes of it. It explains that.
If you're going to try to come up with an argument, please make it more convincing, and don't make other Atheists look like a*s holes with questions like these.
