OK a few points:
-As stated, I have some deeply held principles about how I don't care about my culture or heritage and just want to do things my way. That's something that would likely be consistent no matter how I was raised (also why I know I wouldn't follow Jewish rules if I was born Jewish, barely any Jews in the region here do, so why would I of all people be the exception?)
-I actually converted to my current religious affiliation, I wasn't born into it. So me converting to it from something else isn't a stretch.
-I grew up in a conservative part of North Dakota and still ended up "all liberal all the time". So I'm not a product of my environment in that sense.
Not that I agree, but I can see how all those things might hold true for a white person, though in my experience it doesn't all that often. However, if you were born a Muslim in this country, you're most likely a non-white or likely your parents or grandparents are from a different countries, and more likely to be part of the 'other' than any white person (especially if you're a stigmatized other). That stuff makes a big difference in how view culture and religion.
