I think that the idea that a person is taught to think one way all their life and then within a very short space of time they are expected to throw that out of the window and believe the complete opposite. Yes, if we are well informed, well read and educated we are sceptical and adaptable. However, what about those brought up in very strict homes where dissent is not tolerated? I feel every sympathy for them as they struggle to adapt their views. I imagine that the unthinkingly liberal of outlook are going to be disobliged themselves one day as their capricious beliefs are bound to be challenged and sneered at even as they sneer at others.
I remember a friend smugly pointing out that my children would inevitably challenge my views as they grew up. I was completely OK with that as I have brought them up to be independently minded, to read voraciously, to be well informed and to be able to evaluate and distinguish between fact and opinion and to be logical, empirical and sceptical. What do I care what they think as long as they are rational? So, to be mischievous, I turned the idea round on her to reveal to her own prejudices. I said, 'Yes, it happens to everyone. I imagine your children will be standing as candidates for the Conservative party when they grow up.' Well. The woman literally turned green as she had never considered this angle. Hilarious.
And, no, I have no issues with either gay or not gay. But I know that everyone of my generation will have a context for their beliefs as public opinion and the law were very, very different before the eighties.
