In my opinion being a good parent boils down to three things. First, you protect your child and put their life ahead of your own. Second, you support your child and help them pursue their interests and hobbies. Finally, you teach them every thing that you can to help them enjoy their life, treat people right and make the most of any opportunities that they get. This dude is failing miserably in all regards.
Tossing your kid off a ramp to teach them how to drop in is about the same as watching your kid struggle to drive a nail straight into a piece of wood so you take the hammer and smack them in the face with it. I don't care if it's skating, baseball, basketball, gymnastics etc., any parent pushing their kid to compete in any recreational activity for a reason other than to have fun and socialize can suck my dick all the way down to the balls. They are basically just projecting their own insecurities and failures on to their kids in hopes of some lame form of vicarious redemption.
Shitdad's footage and Layzieyez footage are perfect examples of each end of the spectrum. Give it 15 years and I guarantee Lazy's kid is going to be a hell of a lot more happy than the other kid.
