First. Good point. I used the word "science" in place of "relevant school of academic study."

Cars and swimming pools ARE regulated for public safety. You need a four foot high fence around a pool. You need to pass 2 competency tests to get a drivers' license. You are required to wear a safety belt and not be under the influence of drugs. Now, we need laws that keep the most deadly weapons away from the most deadly people. It works everywhere else.

There is no data on the health of slave owners, especially because they were just rich people. Any rich person without slaves would live as long. Safe, legal abortion is better for society by every measure. Forcing poor women to have children they don't want just increases child poverty and crime and lowers education levels and life expectancies.

I didn't say "ethnic homogeneity" - you did. I'm talking about conservative bigotry and xenophobia manifest in the GQP immigration policy of "Let them die, but don't let them in!" We need better immigration policy, but the GQP keeps blocking it. We need the labor. They need work. Why lock them out? They aren't statistically more criminal. They are often the best citizens, and near half of them vote Republican. People are all equal. Who cares if America changes languages? Or if our culture becomes more hispanic? Doesn't that mean the people with the most merit were those you wanted to keep out?

Honestly, this is way more of my valuable time than you are worth. I won't be responding to you again.
