Based on your Godless libertarian doctrine, homosexuals and those who support it are friends.
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.

But wait, there's more! (libertarians aren't only promoters of perversion, but they're drug pushers too).
1.7 Crime and Justice
Government force must be limited to the protection of the rights of individuals to life, liberty, and property, and governments must never be permitted to violate these rights. Laws should be limited in their application to violations of the rights of others through force or fraud, or to deliberate actions that place others involuntarily at significant risk of harm.
Therefore, we favor the repeal of all laws creating “crimes” without victims, such as gambling, the use of drugs for medicinal or recreational purposes, and consensual transactions involving sexual services
