i suppose this is psychological warfare of some sort...?

if the cavalry fella thinks this is working then he's either a moron or fond of making insulting statements for the sake of making them ( i.e. i'll do this cause i want to insult you, and for no other reason").
or, if it is working, then people he's shooting are morons.

?
so being shot with a pork bullet is worse than beign shot with a lead bullet?

if the person being shot cares, he's an idiot and is better off examining his beliefs than he is fighting for them
