No, I didn't say that's your position, I asked.

The reason I asked is your position that vaccines are of minimal importance for childhood mortality is one the anti-vaxxers take, but I am aware that doesn't prove you are one, so I asked. And I am happy to learn you are not an anti-vaxxer.

I think where your mind is going is a form of Mccarthyism or "guilt by association." In a public conversation, connecting someone to a label like "anti-vaxxer" or "truther," even if you don't make the actual accusation is a form of slander. Then holding someone intellectually hostage and saying "I'm glad you're not X," as if I'm beholden to what you think of me, is sleazy to say the least.

You might not be doing this consciously, but you are doing it nonetheless.

Well, ok, you're right. I should have said something more like, "you are presenting an argument that is normally made by anti-vaxxers, so that makes me think you are one. But perhaps I am completely wrong about that." Or maybe said nothing at all.
