I hesitate to reply, but what the heck.
Did I say what my experience is? No. Nor have I said that I've ever felt powerless as a human individual. In fact, my experiences may be quite similar to yours.
That's not the point.
No matter how you or I feel as individuals, certain historical events have definitely occurred, just like WWI and WWII occurred at specific times. We can read about these events. You can still talk to people about them. The struggle for Woman Suggrage, for example, affected women who lived before, like my grandmother. Similar struggles still affect women alive today. Lucky for you and me, whether or not we care to admit it, the gains they fought for have made our lives freer.
