- Kids under age 8 shouldn't be taught LGBT concepts such as gender identity in elementary schools (read: "Don't Say Gay Bill")

- Code of Conducts in software projects are dumb and ineffective

- Biden shouldn't have used affirmative action to assign a SCOTUS justice

- Forced corporate DEI is dumb and ineffective
