please dont start this shit, let me list off some other institutions: prison, school, college, democracy, the judicial system, and finally NEWSCHOOLERS. honsestly how often do institutions change, they evolve to suit the times,  this is the same close-minded thinking ive been talking about.
oh and if u were wondering what the definiton of institution:
1. an organization, establishment, foundation, society, or the like, devoted to the promotion of a particular cause or program
.....i dont really see how marrige fits in there, i guess it "promotes" only having one partner...BUT WAIT the divorice rate is OVER 50%, so i dont see how that works, i guess the only real thing it promotes is giving half your shit away and getting to see your kids once every 2 weeks.
so if they wanna put up with it i say why not?
