It's fine. We have laws against blowing people up.

Racism is fine as well. I won't date out of my race and if you think there should be a law that I must that's not really freedom. As for hiring or not based upon race there's already a law against that.

The cure is often worse than navigating uneasy waters. Every time you pass a law you give a gun to a bureaucrat.

None of this should be a mystery. Making a bomb is literally something you can figure out with very little research (my friends and I used to blow up cow pastures for fun!).

Racism is a totally different and sadder issue. I don’t have a good answer for that one, but knowledge shouldn’t be withheld because someone thinks it is “dangerous”
