Because let’s face it: as long as divorce is legal, then there ain’t no such thing as a sacred union (not that I believe that nonsense to start with). It’s just a whole lotta fuckbuddies with benefits.
There is one group (based in Va. I believe) that tries to push anti-divorce legislation. For some reason, Congresscritter ignore them. I really wish those guys would get a bigger megaphone.
However, in Texas (of course) there was recently a big bro-ha-ha because a lesbian couple wanted a divorce. Dear me, Texas couldn’t have that! Because allowing these two women a divorce would be an affront to the institution of marriage!
I’m paraphrasing, but not by much, the argument put forth by the forces of pro-familydom.
