First, the article talks about politeness as in "fear of hurting others' feelings" and never about raw fear, as in "fear of getting killed". I was pointing out that your comment was off-topic and offensive.
Second, about the "Islam isn't peaceful" part: Islam does have a set of rules about war, most of them seek to "humanize" war and pretty much disagree with the crazy shit that is done in the "name of Islam". The BBC has a summary of the rules.
Last, I do criticize muslims who do crazy shit or muslims who support people who do crazy shit. I do not criticize them for being muslim, but for being batshit crazy.
(And by the way, when I say that I'm not muslim/theist any longer, it's not because I disagree with Islam as a religion (or any other religion in fact), it's just that I stopped believing in God or gods, and the first and most important condition of being a muslim is faith in the existence of God)
