Very well-put Allourboys.
I think one thing I also try to remind myself is that during my teenage years and twenties, I had all kinds of ideas that I have long since abandoned and am now quite ashamed of. I think the principles were there - equality, justice, fairness, kindness, and I was generally a good person, but some of the ideas I had about things were half-baked and naive (being very kind to myself). Actually I see the same in my DH. He's a lovely person but he's only now in his mid-30s and a father beginning to truly grasp some of the concepts of feminism and equality (as am I).
I will try to raise my boy with the right principles and let him sift through the dogmas, mantras and stances, as his father and I have done.
That said I would never, ever have done anything close to what those Durham scumbags have done.
