Yes they should.
Being parters females wouldn't be able to er... impregnate one another due to nether of them having a male gentile. Males are the same deal, nether of them have an egg. I do think they should be able to for that reason. Although the child might have issues in school if he/she told anyone they had homoloveual parents because of our very very antigay society we have today.
So yeah.
There's my rant.
