There was a time when "skeptic" meant someone who thinks for himself and accepts nothing at face value.
But in the last half a century it has come to mean someone who accepts the status quo and all current "knowledge" without thought or reflection.
I consider myself a "skeptic" under the old definition but now days I'm much more a "crackpot" than anything else since I reject most modern beliefs.
Well...couple of things to unpack there, I think.
1. The original skeptics were more a philosophical movement than anything, and their focus was largely on whether it's possible to know anything. Consider someone like Cratylus. I'm not sure if you're suggesting you subscribe to that school of skeptical thought, or if you mean a more modern style, but not what you see as common usage.
(Note, I'm focusing on the Greek origins, but I'm aware of Eastern schools of thought which independently came to be. I just don't know much about them.)
2. If you're a skeptic in a more modern sense, I think one of the issues that needs to be grappled with is that there is far more to know now (depending on what type of knowledge we're discussing). We stand on the shoulders of those who came before. The further you step back in time, the more feasible it is for an intelligent individual to 'know' enough, or to be able to apply 'common sense' or consistency of principles to determine their position on anything. In terms of scientific knowledge in modern times, though, you're kidding yourself if you believe you have enough of a handle on it (across all disciplines) to argue with experts.
