Only a True Believer™ would find the following argument against gay marriage reasonable:
Because Gravity and Marriage are exactly alike… except that they’re not. One is a natural law of the universe and the other is a social construct. It doesn’t help that they can’t even describe gravity properly. Gravity only goes in one direction? Since fucking when? It’s not about direction, it’s about mass and attraction. If you are standing on the “bottom” of the Earth then gravity goes “up” towards the center. That’s why you can stand on the “bottom” and not fall off. Not to mention that once you get into space the ideas of “up” and “down” start to lose any real meaning.
It’s always hilarious when the True Believers™ try to use science to make an argument. Invariably they fuck it up pretty badly so that you have to be pretty damn scientifically ignorant to agree with it. Alas, there are a lot of people out there who fall into that category. You’ll know them when you see them. They’ll be nodding along in agreement with this video.
