I am curious as to why you call islam a cult, but not your own christianity.
What do you think the definition of "cult" is? According to the dictionary, which most people get their definitions from, any group of people that worship the same thing is a cult.
Further, if you got to Europe, you can see how Islam has turned many cities into disaster areas.
In England and Norway, there are many areas considered "no go zones" for non Muslims. Unlike going down a street in a nice neighborhood in the US or Canada, going in will not only elicit dirty looks, but will likely get you beat up or killed. Even the police will not go into certain areas for fear of violence.
Islam is a cult because of it tenets
In Islam, you can be killed for apostasy (leaving Islam).
In Islam, you cannot say anything derogatory about Muhammed, or you will be killed.
Preaching another religion in a Muslim country will get you imprisoned and or killed.
In Islam disciplinary action includes beating, maiming, stoning, beheading or jail. Excommunication is for minor offenses.
Those who leave Islam must live in constant threat of being discovered and killed.
Based on the above, Islam is a cult. It is the biggest and the most successful cult. It practically reunites every feature of cult. Other cults may not be cultic in some of the above points. But Islam is cultic in every way and it would be a gross mistake to number it among religions just because 1.2 billion benighted people call themselves Muslims.

Hmm I wonder what this reminds me of. Was there some rather popular religion similiar couple hundreds years ago?
