Blow gets hate because of the way he speaks. If he put forth the same concepts and ideas with a lot of BRO thrown in, he'd get less hate. I know am reducing it down in a pretty dismissive way, but it's hard not to see that sort of pattern in the way people react to Blow. It's perfectly adult and okay to talk about matters which are not life or death with sincere intentions and reason. Some parts of the population haven't reached that point in their life where they can do that, and react rather adversely to those who do.
