No offense, but I think that's unfair to those who have commented on those threads and told their life stories. Person after person wrote that they were motivated by the pursuit of religious truth, that they changed denominations because their consciences and their study of church history and Holy Scripture led them to the church which, in their judgment, was the most correct. While many people do simply attend whatever church is handy or familiar, etc. it is wrong IMHO to suggest that this is the main factor in the selection process for most people.
And look...people who call themselves non-denominational have often posted their reasoning, why they made the choice they did; and it was because of something that amounts to wanting to be in step with what they perceive to be Christs intent--no less than those here who chose to be Catholics, Anglicans, Lutherans, Presbyterians, Pentecostals, or affiliate with some other denominational faith.
