Here's the text of the email I sent to the Maryland Retailers Association. I suggest you do something similar in your own words.
I was seriously offended by Jeff Zellmer's statement that the Baltimore "living wage" bill would be "a Holocaust for the retail industry." Not only is that an egregiously inflated statement AT BEST but degrading and horrifying to the millions that suffered (as well as those who survived) one of the most devastating episodes in our world's history. Your group should apologize immediately.
Regardless of your feelings about this bill, that kind of talk should not go unchecked.
