Hmm, in the country of more than 300 million people that's 1 in more than 15,000 americans a year. What's a big deal? More americans actually commit suicide every year (1 in about 8,000) than become muslims.
nothing like some perspective. so between converts for marriage and converts in prison, you probably have 98% of the converts. Add in another 1% for tax or job reasons or something artificially motivated and what are you left with.
