If you could change 4 Supreme Court cases what would you change

[Oldiesfreak1854]

Roe v. Wade
Plessy v. Ferguson
Obergefell v. Hodges
Wallace v. Jaffree

[Oldiesfreak1854]

Roe v. Wade
Planned Parenthood v. Casey
Korematsu v. United States
Wallace v. Jaffree

Although I would be inclined to mention Dred Scott, Plessy, or another civil rights case, I chose not to because the Supreme Court eventually overturned those in a number of subsequent decisions (Brown, Morgan, Boynton, etc.)

Excluding rulings that were later overturned:

1. Roe v. Wade (and by extent, Doe v. Bolton): the Dred Scott decision of our time.  It not only denied humanity to the unborn, but ushered in a genocide of children that continues to this day, all for the crime of being "unwanted" or "inconvenient."

2. Korematsu v. United States: The internment of Japanese Americans during WWII (and, to a lesser extent, German and Italian Americans) not only violated the Equal Protection Clause but also the

3. Wallace v. Jaffree: There's no reason why schools should not be allowed to set aside a time for teachers and/or students to have meditation or voluntary prayer, as long as it is not requiring a prayer or sponsoring the recitation of a prayer.

4. Employment Division v. Smith: It's clear that Smith was engaging in a religious practice that could not and should not be abridged under the First Amendment, yet the Court decided to prioritize the War on Drugs instead.  (FTR, I oppose drug legalization, but when there is a clear example of it being used in longstanding religious tradition, such as this case, then I think that there should be exceptions.)
