I don't get mad at them. It's nice to talk to random new people about religion. Seems like whenever I talk about what I believe they just tell me what I should believe but I've had some decent conversations with some JW's.
Can't really blame them, if they convert someone they are promised the after-life. If that's what I'd believe I bet I would be on your door-step too.
Back on topic about "Evangelical Atheists", it's been stated above. But, yeah it's dumb to go around insecurely trying to convince everyone to your moral standards. I look at it as a battle of a person trying to control the world around them. Which is an insecurity/power issue.
I can't blame them either though. If I believed in nothing, and felt religion was ruining the world around me, and I need something stable to grab on to, I would probably do the same.
Personally I do my best to understand and embrace the world around me. Which includes the differing people on it as well
