Independence Day
I understand liberty to mean: you don’t have to do what someone else is trying to impose on you. It is a sort of negative liberty.
Negative liberty is what the American colonists fought for in the War of Independence.
Nowadays, there are endless disputes about liberty even though they hide as hot-button topics such as Trans and LGBTQA+ rights, global warming and what to do about it, personal health decisions like abortion rights, and the particularly American issues like the right to bear arms and the right to unfettered expression.
