You can know about a downside to doing something, still decide to do it, and still publicly say that there shouldn't be that downside. That doesn't even make you a hypocrite.
Sometimes I drive places. I know that it's dangerous. I accept that risk. But I'll still say people shouldn't be reckless drivers and that we should make the roads safer.
And I certainly am not, by accepting the risk of driving, giving someone permission to drive drunk and wreck into me. That'd be a crazy interpretation, right? So what's the difference here?
