If you can't keep your Billy Graham in your pants, then it might be a good rule for you.
Maybe Graham himself had an issue with keeping his Billy Graham in his pants? I mean, what was his core message here?
1) Women are legit untrustworthy and will make stuff up (a paranoid viewpoint popular with MRAs, bitter divorcee Dads, Red-pilled neckbeards, the alt reich and other assorted losers with a grudge). Or...
2) Graham simply couldn't keep it in his pants? And neither could Mike Pence, or all those other big-ego WASPs?
It seems fantastic that Graham could preach the exact same message as Muslim clerics! The Billy Graham Rule is mad popular in the UAE; they just don't call it the Billy Graham Rule.
