It is "misinformation" that evangelism is part of Christianity? That's news.
The statement was "It's Christians gig to proselytize", not evangelize. I think most people assume "proselytize" means going up to people who don't want to hear it and saying things like "Did you know you're going to hell if you don't Come To Jesus?"
Evangelizing is a much broader term with more of an "attraction rather than promotion" connotation.
