Kenneth has provided useful advice for dealing with rightwing JPP idiots.
The reason why JPP Republicans are idiots:
Anyone with the internet and 5 minutes can find something that thoroughly discredits their version of "the facts".
Even with confronted with contradictory facts, they will continue to fall back on their original arguments, try to change the subject to something they are more comfortable talking about, or start expressing opinions with no factual merit.
What to remember when debating JPP idiots:
Keep them on-topic.
Don't let them ignore your counter-points and then change the subject on you. They're masters of that, but if you can keep them on topic eventually they will just start expressing opinions.
Just ask "Do you have any facts to back that up?" They won't.
Works for me.
