I guess it's probably because of the folks I've lost to the lies of the pharmaceutical cartel's 'medical' industry, all their needless suffering and having to watch them die in so much pain.
And realizing now it only happened that way because of the cartel's voracious greed. I imagine I'm projecting that misery onto all the suffers today, and it does make me angry--all those people and their families suffering so badly, for no reason but greed. *Grr...*
If everyone realized this, there'd be a LOT more rightly outraged angry people, believe me.
