You said: "When rejecting these religions, one is also rejecting forgiveness in favor of perpetual revenge." This is logically incorrect. Your postulate seems to be that if you accept an Abrahamic religion, then you accept forgiveness. The contrapositive of that postulate, which is true if the postulate is true, would state, "If you reject forgiveness, then you reject Abrahamic religions." However, the statement "if you reject Abrahamic religions, then you reject forgiveness" is the *inverse* of the original statement, which is not necessarily true per the rules of logic. In other words, it's possible to accept forgiveness without accepting Abrahamic religions.

Which doesn't even get into the fallacy that the opposite of forgiveness is perpetual revenge.
