I say this kind of tongue in cheek because I'm sure most people would assume it is 1% or less, but I'm sure you are familiar with the concept of self-loathing Jews. Are there self-loathing Mormons?
What if you're active LDS, card carrying etc., but you disagree with some of the cultural things about the LDS church?
This came up in gospel doctrine Sunday in the context of the Romans vs. the Jews and how the Jews had all of these cultural traditions that were wrapped up in the church like circumcision. So if you think ties are stupid, does that mean you hate the LDS Church? What if you roll your eyes at the far right state legislature?
I guess I'm pointing out that this question is a little more nuanced than you think.
