Yeah, I can't really hate Clint. He's not perfect as a dad but point me in the direction of a perfect parent. For all his flaws as a father, Clint getting custody over Josh and actually attempting to raise his child with his diagnosis of autism in mind is leagues better than Borb mainstreaming Chris and allegedly buying his galpals, as well as coddling Chris by humouring his every whim and showering him with electronics etc.
I also can't imagine how difficult it was to raise Josh. Normal children can be a handful, add in Josh' brand of autism. Papa Nips at the very least tries to help his now-adult son despite everything, and it is far from easy to deal with normal addicts without autism.
The only thing I hate about Clint is his sense of fashion but it adds to his character and flamboyancy.
