Some Christians, as well as some Buddhists, Muslims, Jews etc. are mad but can we call all members of some religion mad because of a few people or some small radical groups inside some religion?
I don't think so.
If you see drunk Italian or arrogant french man, what will be your conclusion?
All Italians are drunk and all french people are arrogant?
I don't think so.
Don't judge someone based on his religion, nationality, sex, race but based on his/her character.
Are you trying to reduce the arrogance of the French by not capitalizing the word "french" in your comment above? Or are you simply leaving them their heads, since they are the ones that made the guillotine popular?
Capitalization is like capital punishment. For example. A lower case "i" has a dot on top of it. When a person talks about himself, he says "I", as in "I do it." I should use lower case for myself. The dot on lowercase indicates that I still have my head. Uppercase has no dot. It shows me after I lost my head. That is why it is called capitalized, as in decapitated by government, which thing the French government is popular for.
