This is so wrong on so many levels. First, what kind of shitty human being would do something like this in the first place? I mean, no, seriously??? HOW does anybody think that doing shit like this is OK? There is, like, no universe in existence (even if you believe in infinite parallel realities or whatever) where it's OK to mail people dead pigs and send them funeral wreathes, just because you don't like their freaking NEWSLETTER.
And then beyond that, even among the (hopefully small) subset of people who have no moral qualms about this, who the hell could be stupid enough to think that they could do this and NOT get nailed for it, either by being fired by their employer, or getting in legal trouble?
Everything about this just screams out to me as one more reason to embrace misanthropy. :-(
