I'm not saying that any value judgement is a bad thing. I'm saying that you're viewing your upbringing strictly through the lens it handed you.

As far as I can make out, your argument goes like this:

Strict parenting is good because it produces high achievers. I think achievement is good because I was conditioned to think it was good. I was conditioned to think it was good as a result of strict parenting.

Effectively: strict parenting is good because I was strictly parented.
