I'll throw in my two cents as a Christian.
Evangelism (to my knowledge) is not a denomination. I go to a church that is Nondenominational, meaning just like it sounds, we don't really follow any of the denominations. Not to be confused with Interdenominational, which pulls a little from each.
Anyway. This is largely my church's belief on Evangelism:
"Spread the gospel, and if you have to, use words."
We don't do that whole "I'm only going to love you if I can turn you into a Christian." We don't shove our religion down your throat.
Basically, our hope is that by living the best life we can (from a Christian standpoint ie sinning as little as possible, studying the Bible, praying often, etc.), people will notice that something is different about us and ask us what it is.
With my close friends, I'm a little more open about my faith. I talk about it with them often, and every once in a while I'll invite them to come to church with me...but if they say "no", I don't press them on it. I understand how it feels to have someone try and press religion upon you, since I've only been Christian for three years.
On a separate note, I'm all for separation of church and state. One of the best things about America (IMHO) is that we can worship any God (or gods, or lackthereof) we choose, any way we choose. I also believe that abortion needs to be legal. I would never get an abortion, and I would explain to my friends why I thought they shouldn't get one (although I would support them even if they did decide to get one), but as a woman and a feminist, I have a VERY large problem with the government telling me what I can or cannot do with my body.
Anyway, back to the point. Some may disagree with me, but that's my view on Evangelism. Most Christians are Evangelistic, simply by going on missions trips, spreading the word to friends, etc. It doesn't have to be going door-to-door and forcing people to believe you.
