I don’t think these people would classify themselves as “anti vaccine”, they would classify as “safe vaccine advocates”. That’s the open question which has real science begging this question.
But that is not the point of that article which is about whether google should be engaging in scientific disputes, political disputes, etc.
IN THE ARticle linked above if you care to click through to the internal links in the article you will get some interesting wider information. However. The important part of the article is not that vaccines have un acknowledged safety issues or not but that google have decided to take a position. That leads to google taking a position in any topical subject right?
Just curious, have you read much into the subject? rather than having a cursory knowledge on the subject... Hint. if you do, you might start getting more concerned and be less trusting.
