What's bad about anti-vaxxers isn't that they weigh relative risks and make a decision. What's bad is that they spread wildly inaccurate information about what those risks are, which causes people to make faulty decisions that increase the risks for others in the community.

What you are doing here, is glossing over the underlying logic and falsely reasoning by resemblances. I find this sort of false reasoning flat-out stupid. It needs to be called out so others do not imitate it. (Which is a more meaningful resemblance to anti-vaxxers your comment is exhibiting.)
