Why do Christians answer questions about ity in droves?

The first person that answered apparently hasn't been on here much considering that a lot of Atheists actually do answer those types of questions. But, you make a good point. A lot of the time when they're caught in something they can't figure out or answer, they just avoid the question. I mean, I'm not talking about every single one of them. Quite a few of them do try, and with the topic of uality, a good number of them don't have a problem with us (s). I've also noticed that they kind of leave out other sins; like gluttony, sloth, envy, wrath... well, pretty much all of the original seven deadly ones. A lot of them do those, too. That'd probably be why they avoid talking about them.
