Zeb,
It's difficult and at times seems to be an impossibility; but, it is poison and you must somehow let it go.
They were/are deceived and they knew/know not what they do.
In due time accountability will come due. True, not nearly as speedily as we'd like it, but it shall.
With letting it go comes peace and pity for those who've done you wrong.
God is great, beer is good and people are crazy.
