I suppose that's fair enough, but my experience (and I suspect that of most 'Mericans) can be summed up by stating matter of factly that the number of Christian advocates that have showed up at my door trying to preach their religion far outnumbers that of atheists by at least 10-0.
Sure. But I don't consider "who came to my door" to be the sole determiner of who is trying to forcefully press their point of view on me. Those who ever have come to my door have been Jehovah's Witnesses and Mormons. I've never had a Catholic, Lutheran, Methodist, Baptist, Episcopalian, etc come visit me on some evangelical quest.
But I'm willing to admit that where we live and who we talk to means neither of us will have more than anecdotes based off our own experiences. If you're an atheist, you probably never had anyone who saw the need to tell you (for the -nth time) that you had to read "This Dawkins book that totally opened my eyes" or get visibly upset that the supposed paradox that someone who believes in God doesn't believe in seven-day creationism but rather is down with evolution. Likewise, whoever is out there saving people for the LAWRD!
is likely more immediately worried about your heathen godless soul than my Catholic one.
