I don't go to people's houses and annoy them. I prefer annoying people online where they can't hurt me.

Seriously though, evangelism is a major part of Christianity (we consider the Gospel of Christ to be good news, and we are supposed to spread the good news). Of course, this pisses people off. No one said that evangelism is a pleasant experience. I know, I spend many years as an athiest and Christians pissed me off all the time. I believe it has been this way throughout the history of the church. That's just the way it is. Sorry, but you'll just have to deal with annoying Christians 'till your dying day.
