Coming to this late I doubt anybody will read this but I am surprised nobody has made the obvious point: Many people's social circles contract as they get older. As you mature, it is natural to reach the conclusion that life is too short to spend on some people and that there are other, better things that you can do with your time. What you are complaining about is socialising in an environment that for whatever reason, you can't be yourself (in this case, because you can't correct people when they say something obviously wrong, but it could have been any other reason). So don't. Decrease the quantity of your socialising, increase the quality, and spend your time doing something that gives you genuine pleasure, even if it means doing it on your own.
