You're downvoted because your post expresses misunderstanding.
Roberts rightfully expressed no disdain for same-sex partners, nor did he express it should never be legal.
Rather, it should have nothing to do with constitutional law, (nor really even federal law).
Sadly all of our modern civil liberties are fought for on self-serving platforms rather than on a social framework consistent with civil liberties. In other words, people claim to be civil libertarians, but they act in a way which suggests they just care about an expedient pathway to the ones they personally care about.
This is a very naive view of Roberts own record as a conservative activist and politics more generally. No such “social framework” exists separate from a fierce and persistent demand for it. This is certainly how the wealthy maintain their power.
It looks like you've been using HN primarily for ideological battle. That's a violation of the site guidelines and we ban accounts that do it. Ideological battle is incompatible with intellectual curiosity and this site exists for the latter.
