I see no possible way for what they espouse to be morally responsible. It is very simple: they don't understand much about science. If you are ignorant of science, then it is easy to believe that autism symptoms that develop in your child after they get a vaccine are caused by the vaccine. The obvious flaws in this claim just won't appear to you just like bugs are often invisible to the developers that write them. Unless you've spent a fair bit of time thinking through causation claims and how they've been wrong, you won't have the practice to get this sort of analysis right, especially on such an emotionally fraught topic.
