I am non-denominational christian. My family is Catholic, and I was too, but this is in my past right now. I just don't believe in human authority, and think that we(christians) should listen to Lord's words(The Bible) first.
But it is my own opinion, so I understand and respect that yours may be different
And I also don't have problems with other beliefs (or their lack), this is personal matter and shouldn't be stigmatized
