LOL. I think there's no difference between Liberal Democrats and Liberal Libertarians. To each their own, I guess. LOL. I group them together when talking politics.
The Libertarians believe the government should acknolwedge people's rights of self-defense. The Democrats think those who would seek to be able to defend themselves should be thrown in jail.
The Democrats believe students should be required to attend school lectures about the wonders of 'sexual diversity' and other such nonsense. The Libertarians believe parents should be allowed to control their children's education.
Libertarians believe people should be allowed to keep the money they earn. Democrats believe people should be allowed to keep what other people earn.
Those seem like some pretty big differences to me.
