Oh, I don't know. Spreading the word at my door, injecting him into our politics, adding him to conversations he doesn't belong in, ranting at us on Atheist boards you have no business being in, putting him into our entertainment, attacking people who don't agree with you, damaging our property to "show us", mailing your unwanted literature to my door, getting in my face at the mall to tell me "the good news", putting your ridiculous pamphlets on my windshield, harassing us because we need to be "saved". I could go on for some length here, but you should have gotten the idea by now. These are things that Atheists experience on a regular basis if they are "out". Not many like to admit they are because it can, and has before, had a negative effect on them at work.
All of this behavior is unwelcomed by us. We already know about your *** and have decided to reject the idea of him thank you very much. Annoying us and going on pointless tirades of how we're ****** is not likely to change our minds. Furthermore, it is the intrusive behavior by some Christians that has began to make Atheists more aggressive and activist than they used to be. I know that I am more likely than I was in the past to go on the attack towards any Christian that I feel is intruding on my life. We've had enough of the hate, intrusions and personal attacks we've all had to put up with and are beginning to fight back!
