Thank you. This is a much more intellectually honest response.

To give one example of where this is unclear, consider antipsychotics. Brain shrinkage is a known issue in schizophrenic patients that hasn't been ruled out as not coming from medication due to ethical issues in conducting the associated studies. Some schizophrenic patients also recover without them.

Comparing a valid concern like that to anti-vaxxers seems disingenuous to say the least.
