I am free to not rent from anyone I choose.
And if you refuse to rent to someone because of their race, you're in violation of our laws.
No one is arguing that - I said I can choose whom I rent from, not to, which means that not all discrimination is illegal.
And you just love it? Don't you?
May you one day put a "room for rent" sign up in front of your house only to have a pair of transexuals come a knockin'. I will gleefully be the first one to throw the "law" in your face.
