Their point would be valid if they said "here's an alternative" to diary milk. I dunno, soy? almond? milk. Anything realistic, and they might have carried their point.

Instead, they fly off into la-la land and any hope they had of people taking them seriously goes out the window. The majority of people just basically tossed it off as a publicity stunt and will continue drinking cow's milk.

I don't much appreciate things that go to extremes, in general. If you want to make a point, make it with valid, rational thought.
