No. It is not because of the youtube trolls, but because it's been happening too long. BE CHRISTIAN BE CHRISTIAN BECHRISTIAN is all the bible says, and frankly, I've just had enough that I up and went atheist.
So, you have no reason for your philosophy, beyond a reaction to others? For the record, the Bible has very little to say about being Christian; Jesus (if he existed) was an Essene, a sub-set of Judaism - not a Christian. The Bible has a great deal to say about following the Christ; it has very little to say about following the Church. In fact, if we remove the newer parts (i.e. the Pauline doctrines, esp. Corinthians and Thessalonians), the Bible has more to say
against institutionalized Churches than it does
for them. "Nobody comes to the Father, but through me," is a far cry from "Nobody comes to the father, but through the clergy, who speak with Jesus, who intercedes with the Father, to let you into His presence."
Once again, I agree with the direction you've chosen; just make sure that it's truly YOUR choice, before joining up with one of the more reviled groups in North America (in the US, Atheists are pretty much the only non-hate-based group that can still be legally discriminated against). Just be careful, and consider what you're giving up: the community within the congregation, the comfort of ritual, the solace of faith, etc. If you still find it worthwhile to embrace your Truth, despite these sacrifices, then more power to you.
But hey, take this all with a pillar of salt ('grats to you if you catch the reference) - it is, in the end, your life; not mine to dictate.
