How to say "marriage equality"?


I'm looking for a good way to say "marriage equality" in Japanese.

I like to avoid the term "same-sex marriage" (同性婚{どうせいこん}) in English because
I think that it has an implication that it is somehow different to "regular"
marriage.

Am I forced into a roundabout way of saying it like "結婚が各性的指向に認められました" or
something like that?




Japanese Wikipedia literally translates this noun as 平等【びょうどう】結婚
([source](https://ja.wikipedia.org/wiki/%E5%90%8C%E6%80%A7%E7%B5%90%E5%A9%9A)),
and some Japanese sites introduces 結婚の平等, 婚姻の平等, etc.

I think all of these are valid possibilities you can use, while 結婚の平等 seems to
be the most prevailing, according to Google. But whichever you choose, you
have to explain what it means first, because vast majority of Japanese
speakers don't know these phrases. I personally haven't seen any claim that
同性婚 is a biased term. This situation may change within a few years, though.

I checked several Japanese sites which contains these keywords, including
sites which actively support LGBT. Many of them just briefly introduce these
terms using brackets as (literal) translations of "marriage equality", and
then stick to 同性婚 or 同性間の結婚.

結婚が各性的指向に認められました doesn't make sense to me.
