I just now finished reading a few very moving stories from the News/Activism section of FR and so I would like to post one relevant quote from his book:
The Mohammedan temper was not tolerant. It was, on the contrary, fanatical and bloodthirsty. It felt no respect for, nor even curiosity about, those from whom it differed. It was absurdly vain of itself, regarding with contempt the high Christina culture about it. It still so regards it even today.
Belloc was no politically correct wussie and he called it like he saw it even back then.
