The Pepsi Generatin ( Childish , Judgmental , Bigoted Jerks ?)

So from some of the answers I'm seeing here, If instead of an old lady knitting , if the pie thrower had instead said "You're not a ____________(any ethnic/racial group)" and thrown pie striking person of that group , Still Funny ? No harm ? How about a disabled vet ? or a small child ? Still funny ? Not funny ? Why was the old person getting hit funny ?
I'm sure if a Jewish person had been hit a lot of Skinheads and Nazis would start drinking Pepsi. Not me. Would You ? What audience is Pepsi trying to reach ?
