I have seen criticism of the ad on the grounds that it normalizes bigotry and anti-science to the point of being merely differences of opinion, on an equal footing with the opposing views. It is a valid criticism, but it is no different from the standard media bias, which always favours the weaker position in any argument in order to present both points of view as equal. So in that respect, the criticism is minor and does not make the ad remarkable.
On the whole, I liked it, in that it showed people with unreasonable positions becoming reasonable.
