Are the antivaccinationists getting to Sanjay Gupta?

The tone and choice of words in ORAC’s comments lead me to doubt his objectivity more than Sanjay Gupta’s.

Seems like ORAC’s basic argument is that the antivaccinationists are wrong because they are wrong.

Just because some of the anti group are shrill is no reason to state one’s argument is in a shrill tone.
