How can this be legal?

A a realtor, it breaks my heart, especially working with first-time buyers. They work so hard to save their money, yet it is difficult to find them decent homes to purchase.

Oh this is totally crazy...my God, how are they going to be stopped...I am Canadian and this is all just a nightmare. It proves that they are all clearly mentally Ill with not a feeling to be had for anyone.Intensive care!!!!
