Cornerstone cultural significance
Most of us are raised with that as part of our life goals.
Get a good education, get a good job, find someone to share the rest of our lives with, gather in social groups (couple hang with couples), get married, raise kids with the same values, grow old, play with grandkids.
Not all of us want all of this, but we are well programmed to at least achieve what we can within our own abilities and desires.
I already had kids before I was married to my current wife, both from previous marriage and with her. And then I got snipped. And then I got married. It was probably the highlight of my life. I was watching the wedding video yesterday. Drook, Scott, you looked good.
There will be no more kids. Me getting married did not change any of the current kid's status (at least that I'm aware of).
So, as someone who got married simply because I was (and still am) in love, I understand the desire of others, no matter what gender, to do so.
Beyond that, I can envision end-of-life issues where I'd want her voice to trump my families. Marriage gives her that right without forcing any additional paperwork that can be challenged in court, which is a very common problem with gay couples, especially when the birth family is anti-gay and kicks the partner out of the hospital room.
I know you don't care, since it is all so alien to you. You'll keep fighting and bringing it up, and we'll keep countering, since you will never see the world through another set of eyes. Oh well. BTW, your use of the phrase "all that is holy" is pretty telling.
