It does seem like ‘special privileges’ to expect the state to provide you with a risk free father.
There are risks of STDs, lies, let downs, custody battles, etc, when people want to make babies (or for heterosexuals, when they make babies by accident too).
Why should lesbians not have any of those things? Why should the state provide this guaranteed hassle free man to father their children?
It’s ‘enhanced rights+’ they feel entitled to. They don’t want ‘equal rights’.
