What does it mean to be a Liberal?

What does it mean to be Liberal? This question has been bugging me for a while now! Does it mean that you are pro-choice for everyone or you are just redrawing the line to when you can – at max – make those choices?
There is another dilemma; I am not sure how it connects to this, but let me spell it out here! If you do something in hiding, it is wrong – the very way in which that act is conducted means that it was something taboo, thus the hiding! Fair enough!
But apparently, things which are not wrong – from a normal, rational, liberal point of view – but are viewed wrong by the assholes that are the conservatives are also wrong and should not be acted upon in public!
So then where does it leave the space for the liberal person? Where is the space to do what you think is right and has no harm in it?
What is so wrong in going for a walk with a friend in a park?
What is so wrong in having lunch with a guy?
What is so wrong in trying to live an independent life?
What is so wrong with realizing that you don’t have the marriage gene?
What is so wrong for doing what you think is right?
