A lot of people (including the original cast) had those feelings. I was just at the right age to welcome more Trek with open arms at the time. I was still a huge TOS fan, though. I will say, though, that my friend told his dad that I was a Star Trek and his dad said, "You mean The Next Generation, right?" quite accusingly, suggesting that no "cool" person would like TOS. Yes, according to much of the general public, TNG became "cool" to mention in the open. Just think about how many people touch their chest when they see a TOS delta patch.
