What does Dr even mean anymore?

So, the way I see it is, if you are a college professor you should be able to speak properly... ESSPECIALLY if you are a Dr. I should never have better grammar than you and constantly correct you in my head when you speak. I understand you have all this experiance or whatever. But, I find it hard to take you seriously when you create words like acultration... you missed a letter which is an entire syllable ... WHAT THE HELL!?
