I've thought a lot about that over the years. And come to some conclusions. Among other things - - -

Acceptance means the realization that something isn't personal. That's all. I happen to be an alcoholic. Nothing personal, I inherited the predisposition, then fed and fostered it. In the genes, for starters. Actually, there is nothing personal in this world. (The explanation of that is too long to go into, and completely out of reach of people who think in terms of winning and losing.)

There are many, many things I can accept and still work to change. My alcoholism, for instance. Acceptance does not imply a passivity regarding that which is accepted, only the realization that it is reality, and there's nothing personal in it.

Tolerance is allowing another person the right to their ideas. It doesn't mean that we can't disagree, but that they have to right to think that about which we do disagree.

As I said, these "definitions" are beyond the ken of many if not most people but work for me.
