Feh. I have no pity for anyone who decides to get married. It's their decision. Their foolish, foolish decision.
Depends on those getting married. If they're expecting everything to work out and be perfect, or if they're willing to throw the marriage away just because they can't get past either their personal hangups or their respective idiosyncrasies, then yeah: they probably shouldn't be allowed to reproduce. And they shouldn't be leaving behind mounds of paperwork that certain title researchers will eventually be rooting through, either. (For those interested, I poked a bit of fun at this in an old blog I used to have, circa 2010. >^_^< ) On the other hand, if they're anything like my parents--who will be married 47 years as of this coming September--then I can't really complain. I was the end result and I turned out reasonably well because of them, despite the fact that their personalities tend to clash now and again, so calling it "foolish" in that event is stretching it some.
Eh. I've always seen marriage as a horrendous concept anyway. Just the mere thought of having someone you are legally bound to... it disgusts me.
It's up to you to see value in it. I am not saying you can't. I just never saw it as a good thing myself. I honestly wish for it to never happen to me where I end up married.
