... except that saying that islam doesn't correspond to 99% of the population's beliefs is so hella' wrong it actually is a lie by just about any metric you care to use. Saying that the folks making that claim are white supremacists is a pretty decent attempt at guessing why they believe it. Might be factually wrong at the end of the day, but positing the root cause is that ain't dumb by many measures of it I've seen.
There's significantly more similarities between islam and christianity than there are differences, and by extension that puts it in line with quite a lot of this country religious and not.
E: Though to be clear, the devil's in the details and exceptions more than commonalities. Only problem there is we legislated various degrees of acceptance or protection for a lot of those exceptions long before muslim was a word most of the population even really knew the basic nature of. Harping on a lot of them (if not all) kinda' falls flat when stuff like 14 year old marriages and crap were legalized for christian denominations.
E2: Though largely unrelated to that, apparently the PR referendum is currently looking extremely inclined towards statehood, with something in the upper 90% with about half the vote counted. Participation in vote's also apparently low as hell, but... still. It's looking a lot like we're going to have a petition to put another star on our flag coming up in the very near future.
