Re: 61 - good luck.
I see some posts on the thread from a poster that suggested that President Trump holding a glass of water with both hands like a child may have been trying to send a message to people about water safety. When you are dealing with that level of speculation, it’s challenging to educate and inform.
It is challenging.
My main reason for taking time to refute antivax nonsense is to reach people who might think there is a basis for it. By showing them the real science and the opinion of the scientific/medical community, they are empowered to reject the antivax nonsense and make better decisions about their health. In addition, I actually learn quite a bit myself doing these refutations. The antivax blogs are usually (loosely) based on a real study. They rarely give any links to the study, but since I'm an experienced researcher, I can almost always track it down. And then I learn something new by reading it.
