Why does anyone convert to Islam?

[Anomalocaris]

Conversion to one specific religion rather than, or from,  another is often the result of unscrupulous proselytizers of the winning religion ruthlessly capitalizing on the fact that their insufficiently thinking victims happen to be familiar with the contradiction of, and iniquities perpetrated in the name of, or by the adherent to, the other religion, but not of their own.

Think of why Nation of Islam gained black adherents in the segregationist and predominantly Christian America.
