Putting on my mod hat as well. I understand that this is a topic which some are passionate for and some against. I am passionate about this topic and to avoid confrontation or offending others I have stayed out of quite a bit of this.

I just want to say that personally I think that if you have information you want to share with someone who has a differing opinion, please refrain from pushing it too hard. Others have made their decisions not based on mal-information but from the information they have chosen to agree with. For instance you can read information that is pro-vaccination and it may speak true to your heart as a parent. Well done, you have made an informed decision. Now I have read information that is anti-vaccinations (and certain ones yes, but I'm not getting into that arguement) and have made a decision accordingly. What someone says or quotes here may make me look further into my decision, but what has been shared here isn't anything new either.
