Are Coldtowns necessary?

Are Coldtowns the answer?
Some people would say that without Coldtowns  we would all become food for Vampires. But I would disagree, for thousands of years now humans lived perfectly fine without knowing about Vampires and what they did after the sun went down. The way I see it, if it wasn't for that no good Casper Morales, we would still be living in our peaceful imaginary state of ignorance. Vampirism wouldn't have spread and because of that no one would know any better.

Would we find out eventually that the tin foil hat wearing conspiracy theorists weren't wrong? Maybe someday but as I mentioned above, the issue is not the Vampires, but the rate at which Vampirism was spread in the past decade.

As I have said, I am not here to provide you with all the answers you seek, but I am here to help get the conversation started; To make you start thinking. Argue with me, raise points that you feel would prove me wrong, but start talking don't let shove this issue in a coffin and forget about it.
