Correct. That's the entire basis of the soapbox.

Well, if we are really going to try to shoehorn this example in, it would be more apt to say that if you hit your own kids, that preaching against raping your own kids would be untenable.

There's a few different angles here. If you complain that hardcore drug takers can't control their addiction, that would be untenable as you have an addiction.
