As a relativist, I don't have a horse in this race. As someone who grew up Catholic and still considers Christianity as his personal beliefs system... I think there are better things to do than try to evangelize on a random internet forum, in random threads, to random people one does not know the personal histories of. Quoting Bible verses with vague, generalized intentions of "saving" someone never helps. If someone is asking for the advice of a Christian on a specific matter, sure. Use specific verses that specifically answer the question. If someone is making fun of you for being religious, however, you should probably stop trying to be religious at them. It probably isn't helping your cause. In my experience, belief systems are changed due to events in a person's life, not because someone was preaching at them to believe something else.

That's just me, though. *shrug*
