Once again, you're either assuming or acting like this is all something new. As I pointed out above, this is not new. The "arguments" of your blogger are not new. We have seen this ad nauseum, and it has been disproven ad infinitum. You claim we are calling anti-vaxxers idiots without trying to understand them.
Not. Remotely. True.
We understand where they are coming from, they've been proven wrong repeatedly, but they ignore all evidence, logic and reason, but instead start from their desired conclusion and grasp at ridiculousness to try to prove that conclusion. It's an exercise in futility.
Thus, we think these people are loons, not because we don't understand them, but because they are, in fact, loons. Some of them are really nice loons. Some of them are in my own family.
