It's not crazy to think that I won't be served meat if I'm going to a house of a vegetarian. It is however crazy to think that I will be stoned in that house for having eaten meat in the past.
And it's absolutely bonkers to think that I could be driving on my business on the road that just so happens to pass through some property belonging to a vegetarian, who will drag me out of the car and stone me as "a perpetrator of Gallinaceous Ordocide" or something.
