No, I mean like people who "point out" the evidence for evolution by looking at Creationists and saying things like, "goddamn but you're a moron! How is it that you're allowed to breed? Someone should put you down for the good of society!"
Well that's good. Maybe you should take all your hypothetical straw man friends on a party cruise.
Make all the excuses for anti-social behavior that you want, but the fact is if you're being an asshole to someone for being wrong, you're only serving to make the problem worse, not better.
You might want to look up some of the outbreaks of diseases that have happened recently.
Oh, you won't, will you. Because actual damage to actual people doesn't fit your hypothetical straw man.
Anyone who refuses to get their children vaccinated BECAUSE I SAID THAT JENNY MCCARTHY DOES NOT UNDERSTAND BASIC SCIENCE is not going to change because I don't state that.
That is what a "zealot" is about.
Jenny McCarthy isn't stopping you from getting your kids vaccinated, and being a dick to her and her kind for holding a certain viewpoint is only going to make them grasp it even harder.
Look up "herd immunity". They're increasing the risk by NOT getting the vaccinations.
Which is why there are outbreaks of diseases such as measles now.
Facts. Not feelings. Measles will not care about your feelings.
