You can read from people who have studied global warming for 20 years. You can find many people who have done this. I was very aware of it 20 years ago as many were. Now you can believe it is all political but that is absurd. One side you have a 99% of successful scientists agreeing with and other 1% you have Youtube quacks.(made up #s but probably not that far off these days) I don't think they're all grifters some genuinely believe their nonsense. Take any scientific position that impacts society and you'll find someone with their biases against it. Those who strongly identify with independence tend to follow those types. You know, the rebels!
Not sure what to make of the death penalty. Lots of hard right people not for it because they don't like the state having that much power. I agree with your stance.
The problem with politics is most people who are strongly on one-side identify so strongly they have to defend every little thing with whataboutisms. They're unable to take the criticism like they should. Simpletons.
