Who are these people, and what has happened to this board?

I admittedly don't post every single day, and post in spurts, sometimes going longer periods of time where I avoid it because it becomes all consuming, and puts me in a negative place, but over the course of the past year or so this board sure seems to have been inundated with leftist filth. That's as obvious to me as anything, especially dating back to when I first started posting here in 05.

It's certainly not a sampling of people around these parts, that's for sure, and not what Ive seen represented over the course of me posting here. What gives? Is this just alters trying to inflate their numbers and true representation, have they recruited well from other sites, or is this really just a sampling of America these days going further and further left, especially amongst the younger more susceptible minds who have fallen prey to leftist indoctrination?
