Abortion, marijuana legalization, gay marriage
Abortion is something that should happen. Mothers have the right to choose whether they want a child or not. It's possible the child could die anyways if the mother is not suitable, simply causing it more distress. Besides, there's too many damn people on the planet anyways.
Marijuana should be legalized for the simple facts that it's a medical supplement, it's not as poisonous as nicotine (which is a neurological toxin) and smoking it causes no harm to you, save for the tar in the tracheal and bronchial cilia.
Homoloveuality is a personal choice. We like to think of the world as a place of hard, defined lines, such as loveual orientation and other stuffs. And of course, there is the excuse of 'it's not natural.' There is nothing more natural than uniqueness and diversity. The polarization of one group of people can, like-wise, be argued as practically racism. The government should not be allowed to step in and determine whether two people can be devoted to each other or not.
