Difficult to say, really. My mom pushed the "boys don't cry, you must be brave and take it on the chin, and not act like a girl" mantra, but that's probably because my dad left when I was 2 and she had to play both roles and this was her way of minimisng my chances of being picked on. IT's also probably representative of the 80s when I was growing up. As I grew older, she would make an occasional comment like "I wouldn't mind if one of you were gay" to my sister and I if there was something about it on tv or whatever. So it seemed pretty liberal. 
Which made her OTT hysterical reaction to my coming out all rather puzzling. And to be honest, it's never quite come right again after that.
The extended family is another story; not liberal at all and most of them still don't know about me. So in all probably a 6, I would say. 
I live in Cape Town, and spent most of my life here, and it is probably the 2nd gayest place in the southern hemisphere after Sydney and definitely the gayest place in Africa. Still, though, homophobia is quite rampant in large chunks of the city and the country as a whole, even though gay marriage is legal and was pushed through parliament. It was an overwhelming majority Yes vote, but to be fair the ruling party had a 70% majority and instructed all members to vote Yes. So I'm sure the law does not adequately represent the feelings of the country at large. So that's probably a 6 for Cape Town, and a 3 for the rest of the country. 
And of course a big, fat 0 for Africa as a whole.
