If you believe people should have a freewill to take it or not, there is no line.It is hard sometimes to know what to say without the crutch of ideological scripts to run... but I manage. Just speak the truth as best I can knowing I'm not any more or less infallible than anyone else here.
I acknowledge there is a chance, however small, of there being an adverse reaction, maybe short term, maybe long term, severe/not severe, to one or more of the 3 three vaccines pending approval right now. I get the fear of taking them. And people should have the freewill to not have to take them. The part that I find hard to negotiate is just where you then draw the line with people who don't.
