No the solution is not death. Thats is such a lazy conclusion. If you know someone has a really terrible and dangerous opinion, you dont have to attend their tech talk. Just dont support them in any way personally. Its that simple.
"A person like that does not belong in our society much less should be given my time."
What you're saying now only covers the last part of your statement, what about the "does not belong in our society" part?
And why are you evading the questions about what effects these type of statements have on the 1/3 or more of the US that's targeted by them? You really think that's a free action?
