“conservatism opposes rapid change.”
Conservatism opposes rapid change of that which has passed the test of time - it doesn’t say that when you’re pushed into a well you must climb out only slowly.
William F Buckley offered this:
Liberalism favors fast, reckless change. Conservatism favors slow, stodgy change. You will find fervent advocates on both sides who hate both definitions, but won’t offer a better one.
