Good point. Here is a definition pulled from a dictionary... marriage >noun 1 the formal union of a man and a woman, by which they become husband and wife. 2 a combination of two or more elements.
I can marry two boards together with a nail...or two pieces of steel with my welder.
What definition do we want to use and why? One reason is the formal establishment of a family unit. Men and women seem to have a better chance of generating offspring than other combinations but what do we want a "family" unit to be?
If a man can marry a man, I suppose it wouldn't matter if they were brothers or father and son would it? If a "family" can be any combination of people, why limit it to two? Couldn't it be 3, 4 or 50?
Why should we even limit it to people. Why couldn't a person marry that wonderful dog that they love so much?
ok so if we're going to completely remake the concept of "family", you tell me where we should go with it and why.
