Religion made me hate the concept of forgiveness

Forgiveness was a one way street for me growing up. For some reason, my parents decided that any offense committed against me was forgivable at worst- more often than not, justified because of some minutia, up to and including 'you were breathing wrong'. When they decided an offense did require forgiveness, I had to forgive immediately and totally. There was no room for things like "I forgive you but I don't trust you" or "I forgive you but I'm not doing favors for you".

When I messed up- or they thought I messed up- however? It was an indelible sin born purely of spiteful rebellion, and they needed time to forgive me, layering on punishment after punishment.

I tried pointing out this hypocrisy multiple times, and every time it was dismissed, sometimes with a flippant 'oh, your life is so hard!' or 'we're trying to make you into a mighty man of God'.

I was not allowed to defend myself. Oh sure, they would say 'you need to defend yourself next time', but that was a trap- to defend myself was to assume I had the same right to dignity and respect that everyone else did.

This upbringing taught me the three most important virtues in life, however: Anger, Hatred, and Unforgiveness.

Anger: the wrongs done unto me were deliberate and with the sole intent to cause harm, and I have the right to react with force when someone attacks me.

Hatred: the people who hurt me proved who they were and I don't need to dig deeper on their behalf. If they act like an enemy, I will treat them like an enemy. I am justified in wishing harm on them, and refusing to take any action that would mitigate harm done unto them.

Unforgiveness: just because someone hasn't had the opportunity to hurt me again does not absolve them of past wrongs. Furthermore, the people who are spouting verses and parables about forgiveness are nearly always the ones looking to plunge a new knife in my back.
