Neither of my parents care enough to be honest. It's none of their business.
I think the generation before us (and much of the older generation) are very skeptical and conservative especially when it comes to sexuality. I grew up in a household where if two people kissing popped up on the screen, we would all rush to change the TV Channel and talking about sex/sexuality in general was just frowned upon. It's only logical to assume that they would be less receptive to the idea of homosexuality as it was regarded as an illness as they were growing up.
