Maybe you need a better definition of liberal:

broad: showing or characterized by broad-mindedness; "a broad political stance"; "generous and broad sympathies"; "a liberal newspaper"; "tolerant ...
having political or social views favoring reform and progress
tolerant of change; not bound by authoritarianism, orthodoxy, or tradition
a person who favors a political philosophy of progress and reform and the protection of civil liberties
big: given or giving freely; "was a big tipper"; "the bounteous goodness of God"; "bountiful compliments"; "a freehanded host"; "a handsome allowance"; "Saturday's child is loving and giving"; "a liberal backer of the arts"; "a munificent gift"; "her fond and openhanded grandfather"
a person who favors an economic theory of laissez-faire and self-regulating markets

Most of us who favor change are liberals - we are tired of the status quo. Has nothing to do with smoking pot like hippies. Whoever said today's liberals are yesterday's hippies is anti-change and trying to damage any progressive movements in this country.

What is wrong with the woman paying for her half of the bill? When women go out with other women, we split the bill. When men go out with men, they split the bill. If you have specific concerns with this then you should talk to her about it as we don't know what she is thinking.

Personally, when I am not into a man, I insist on paying for my half of the bill and then I don't owe him anything. Paybacks are a *****.
