Non-sequitor. We were talking about legal and you jumped to moral. I don't believe that anybody should have legal consequences for speech that doesn't incite violence or libel.

Even with moral, I'd argue that the consequences have to be reasonable. It's not reasonable to take advice about vaccinations from anybody except a medical professional. I eat junk food and I tell people it's delicious. If some of them hear me say it's delicious, eat some, get fat, and die, I don't feel morally responsible - take advice about your diet from professionals, not from me.
