What's wrong with being 25?
Nothing. But much of the "Shook the world moments" of tv happened way before you were born. You guys are listing stuff that wasnt ground breaking or world shaking. "Best of Both Worlds" for example was great but it didnt shake the foundations of the general tv viewing public. Many people of your generation and even mine have never seen it. But All in The Family was seen by my generation (though I was only 1 when it first aired) the previous generation and even yours now. Its widely know.
No offence but I find people arrogant who sort of talk down to people who weren't around in a time when certain things happened. It just comes across as saying that the younger generation doesn't know anything.
I am VERY aware of a large number of things that have happened, past and present, because I involve myself in entertainment related things from then and now. I am sure events like the Moon landing and Lennon getting shot, things like that, are well known by a number of younger members in this forum. We just name things that haven't been mentioned yet or simply things that just stick out in our minds. That doesn't mean that we have no clue as to what happened before we were born.
You said yourself that you were only a year old when All in the Family first started so it's not as if you even remember the shocking events that took place at that time yet you somehow feel the need to use that as your example and then proceed to basically tell us younger people "pfft, you guys have no idea what's shocking".
I'm not saying that was the point of your post but that is how you seem to be coming across in this thread. I'm not the only person you've quoted and said "that's not shocking" and proceeded to give your example. Everyone here is from different times and we all have events that stick out in our minds and all are shocking in one way or another.
