It's true that there is no bigotry within Islam, but when Muslims gain political power in a country, the bigotry displayed against non-Muslims makes KKK-style bigotry seem like a tea party.

"No bigotry within Islam".

Tell that to the thousands of Pakistanis, Bangladeshis, Indonesians and Muslim Indians working in Saudi, Kuwait, Qatar and the Emirates. They work like dogs for a pittance and a lot of times get no pay at all for months.

In fact, there is bigotry within Islam. Arabs look down on non Arabs, and to the dismay of some black African Muslims in the Sudan, they are referred to, and treated as "abed" which means "slave". In Arabic, it is synonymous with "black". There are also numerous other instances of intra Islamic bigotry.
I would describe "dar al Islam" as "Anarchic Tribalism", in which to outsiders they are one ummah. Within themselves, it's "I against my brothers; my brothers and I against my father....etcetera.
