I'm not saying he's not misguided. The school thing could just be him feeling the need to repeat himself because it makes him feel like he's doing "something" and he knows that encouraging her to go to school is a very smart thing. Selling clothes is a way to keep her near and retain a bond and even increase the existing bond. People share their opinions whether they are right or wrong. Everyone thinks they are right or they wouldn't state the opinion in the first place (one would hope). But lots of very naive and misled people shout the loudest even though they have little of value to say. But we all have a right to state our opinion, even if it's wrong.
