Agreed. The point the professor makes is "Where does it stop?"
The private business owner should be allowed to discriminate based on any means he/she wishes. It should never stop. However, I would stop shopping there.
In the corporate world, it's called "project creep"..once they ban smokers, they can ban fat people on the basis that they already ban smokers for health reasons..once smokers and fat people, they go after the next group, whoever that may be..and on and on and on..
This is the primary reason I refuse, under any circumstances, to use those "discount cards" at the grocery store..much as they say they don't, I believe a record of what is being purchased per card is being kept..based on this article, what's to prevent a possible future employer from obtaining this list, then determining they won't hire me based on what I buy because they don't deem it healthy?
That's why the "Where does it stop" come from..
Cameras in your bathroom, etc etc.
Remember where it started? Elevators. No big deal we were told. It makes sense, the little NAZIS cooed. Now look where we are.
