Why do I care?

The above picture explain exactly how i feel when debating with Christians online. Like I said in my last post, I've tried to stand back and let the religious be...but when they troll Atheist sites it pisses me off. I never have commented on ANY Christian site, why can't they give Atheist and Anti-theist  the same curtsy?

Many people (including some atheists) ask me why i bother to fight against religion. I wouldn't care so much if they didn't push politicians to push religious beliefs in laws.
