STUPID NFL rules?

ok, i have a major problem, why does the NFL care more about the QBs then other players. its stupid. you cant hit a QB in the head but you can hit a WR as hard as you want anywhere you want. when half of the CBs and WRs are smaller than the QBs. i think its time that the NFL and the QBs grew some b@lls and take a hit the same way the rest of the players do. what do yall think? i mean, last time i checked football was a contact sport. i think the same rules should apply to QBs and RBs. i think the QBs need a good smack in the head every once and a wile. do you have any input in this question? do you have any gripes about the NFL rules? put them on here!
