I put it to you that the conservative opposition and bigots are very uncharitable at the outset, in interpretation of messaging from the other side. In this case they didn't have to do any work, it was literally said for them.

Don't forget that working people and moderates are the ones you need to convince. If people didn't change their votes, election outcomes would always be the same. Educated people tend to be more committed to a worldview (and overconfident), whether left or right. They are listening when you mock egg prices.
