It is unacceptable behaviour by other people.
When someone acts intolerably, they are taking a liberty.
In actuality, I cannot take a liberty but I can give away my liberty.
My liberty is a choice.
It is my freedom of choice.
I can choose my liberty or I can choose to give it away.
I cannot take a liberty from another but they can concede their liberty to my choice.
Expecting someone to cede to my choice, is taking a liberty.
I am not free to choose for other people.
