You should be careful about placing the blame on skeptics for misuse of their opinions by nutbags. Because the nutbags would have likely just latched onto something else. They didn't reason themselves into their crazy beliefs. So removing reasonable opinions isn't going to change their beliefs one bit. The conspiracy theorists often latch onto proponent's factual claims and misinterpret them as supporting the conspiracy theory. A lot of conspiracy theories re vaccines will quote CDC, WHO, research papers, etc. that aren't skeptical.
