Offense is different from pointless insult. Telling someone they are dumb, idiots etc just because they believe in god will not lead the debate anywhere. I support free speech, and freedom to offend - But people can be offended at anything. However, if you do speak your opinion you are responsible to provide proof and explain it clearly, and you should also listen to people who think differently.
Using the example of killing in the name of religion - A month ago I read a study about it and for the most part killing in the name of religion is mostly influenced by nurturing and outside variables - The only exceptions are the big three monotheisms, those are the religions that drive people to kill more in the name of religion and sometimes it is even the only cause. Even so, I don't think you can kill solely in the name of religion and isolate the environment and circumstances. I gave the example a few days ago - It isn't a coincidence some environments create more Jihadists than others

Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
