Can we please just skip to the part where you tell us how you feel about vaccines?
There is a reason for why "assume good faith" and "please try to assume the strongest possible interpretation of comments of others" are a part of HN comment guidelines. Instead, you just immediately jumped to an assumption that the reason the grandparent comment author is not a fan of him is because BillG is pro-vaccines, and the author is an anti-vaxxer.
