This is what happens when you confuse language.
Prior to the 1980’s, nobody spoke of a homosexual partnership in terms of “marriage,” not even the people advocating for legalized unions. Somewhere along the line, advocates appropriated a religious term to describe it. Now language becomes vague, and previously clear lines that would be hard to cross become fuzzy and easily crossed.
Separation of Church and State does not only apply to the Church interfering in the State. It’s a two-way street, and unfortunately, the current leadership of the Democratic Party does not understand this. How far the Democrats have fallen since the days of JFK.
