That's what I'm saying. In the US, conservatives actively worked, and still work, against personal liberties in terms of LGBT marriage rights. That was my point.

Be cautious of the definition trap.

People have different definitions of marriage. One person ‘defending’ one definition looks like ‘actively working against’ another definition.

E.g. in some cultures, by definition, a marriage isn’t valid without a male/female sexual act (the only kind that can lead to procreation, by definition). This axiom is held by over a billion humans for example.

LGBT marriage, at least in the United States, is a legal definition that need not have any bearing on how 'marriage' is understood in any other context. It came about purely as a legal hack, to address the needs of people who sought some legal acknowledgment of their stable companionship. The existing law and custom provides this wrt. "married" couples, and this was simply extended wholesale by sort-of pretending or establishing by fiat that two people can be 'married' no matter what their gender, as far as the law is concerned. It's a sensible mechanism that has plenty of other uses in law and policy.
