Since I was disagreeing with you yesterday, just for the heck of it I'll do the same today by saying no they won't get the idea by being punched in the head repeatedly.
I say we settle this by doing a study. We'll a large subject group of liberals (at least several thousand to ensure scientific integrity) and start punching them in the head as many times as possible. It's the only way to find out for sure who's right here.
I wonder if we could get grant money to help us fund this study? Maybe we could even draft Ceasar Chavez to help with some of the impact studies to find out exactly how many PSI need to be applied for best effect... although I'm a guy who normally doesn't like others doing his work for him.
Luckily, liberals here in Cen-Tex breed like deer in Lakeway. Plenty to go around.
