Maybe? I don't usually read those threads. Link?
On the left, you have disputes about markets, social issues, voting, "money in politics," and a lot more. Probably Israel too. On the right, I'm often struck by how people with apparently opposing views never seem to argue with each other. For example, was Obama secretly a Muslim or an atheist? Those were very claims, but people making them never got into it. Or a lot of rightists here say they support SSM or UHC, but they never argue with other rightists who support the GOP positions on those issues.
