Here is the quote from one source and I do stand corrected:

If you're not a liberal at twenty you have no heart, if you're not a conservative at forty you have no brain.”

I strongly suggest that the source of that quote is wrong. In Churchill's day, “liberal” didn't mean what it does in the U.S.A. today. In fact, it still means something quite different in most of the rest of the Anglo-sphere.

U.S. leftists co-opted the word “liberal”; because they knew better than to call themselves what they actually are.

Churchill would have said “socialist” — and that's how I've always heard the quote repeated.

What's the opposite of “stand corrected”? IMHO, you were right the first time.
