Such a necropost x__x
That said, I'm not sure how old you are, but it was a much bigger deal then than it is now (even just a few years later).
I'm sure it seems 'obvious' to you that same sex marriage is no big deal, but to others it seems equally 'obvious' to oppose it. Both sides get instant gratification when they announce their views and people can chime in with, "yeah, our opinion is the obvious way, theirs is wrong."
Also, even if that 50% divorce statistic is true anymore, that's still leaving 50% of marriages being life long. And keep in mind that a lot of the divorces are from already divorced people. So ex. If there are 64 marriages and 32 divorce and remarry and then 16 of them divorce and remarry, etc, then there would end up being 127 marriages of which 63 end in divorce, but all but one ends in a marriage that lasts.
So like 98% of those couples end up married for life, resulting in a roughly 50% divorce rate
From this report
on baby boomers:
"Approximately 42 percent of marriages that took place between ages 15 and 46 ended in divorce by age 46."
The first report on this CDC page
indicates similar rates and that marriage and divorce are declining.
Plus, if a marriage is leaving you feeling terrible and it can't be fixed, why stay in it? People grow and change and divorce can be the right choice. The stigma of divorce is pretty f'd up in my opinion.
In my opinion, marriage should be between one person and a harem of calculators. Polyamory ftw. As long as it's consensual, you do you.
