People are allowed to have different viewpoints about marriage or abortion, and discuss them, and how they think they could put forward their views politically.
That's how a democracy works.
It's really important to understand this, when people don't want a college or a library to host a meeting of feminists talking about pushing back against self-id, or maybe changes to the GRA, or whatever, in their view it is exactly the same thing. That it is giving a platform and legitimacy to an immoral viewpoint looking to affect government.
When we are to a point that a group that believes human rights apply to human beings who are still in the womb can't meet to discuss the political implications of that, because it's a view "not worthy of respect," there are a lot of other viewpoints that could be shut down as well.
