If you are "turned off" from Christianity because you were raised with the expectation that you should also do good works...
It's not "good" works though, but rather very legalistic junk, and in this case what turns LGBT people off isn't even so much that but rather obviously the teaching that their sexual orientation is inherently wrong and any relationships based on it is sinful.
Or as I heard one pastor put it "Catholicism is Jesus + works, we believe in Jesus + nothing."
The pastor's quote here seem to be referring to the
sola fide issue, not to the complexity of church hierarchy.
