WTH has happened to people who used to have a functioning brain?
They join websites like DU and their brains stop functioning. They go there and talk shit about things about which they know very little.
Like natural immunity.
Even a DUer person should be able to understand that if it's good enough for an entire species since before recorded history, that it's good enough for modern times.
The combination of arrogance and stupidity from leftists and their ilk and fellow travelers, is the sort that would eliminate them from the gene pool if society weren't so bubble wrapped.
