Anyone willing to indulge a radfem for a moment?

Since you seem to be asking after what the Libritarian Party believes, I would suggest reading through their most recent platform. Many of your questions are answered there.

For example, does this help address your second and fourth question?

1.4 Personal Relationships

Sexual orientation, preference, gender, or gender identity should have no impact on the government’s treatment of individuals, such as in current marriage, child custody, adoption, immigration or military service laws. Government does not have the authority to define, promote, license or restrict personal relationships, regardless of the number of participants. Consenting adults should be free to choose their own sexual practices and personal relationships. Until such time as the government stops its illegitimate practice of marriage licensing, such licenses must be granted to all consenting adults who apply.

If this piques your interest I'm sure there's much more complete discussions of the topic elsewhere in lower-case 'l' libritarian circles others might be able to reference.

Thanks for reaching out with an open mind!
