Hi Koji,
I can certainly understand how you feel, but like others have said, maybe just take a break?
I always like to say, CC comes and goes in waves. The crowd is always changing, sometimes month to month, and surely year to year. Sometimes I find myself being able to relate to "the crowd", and sometimes I can't, but don't want to interfere, so I usually step back during that time.
I understand what you mean about finding more and more polarizing views and criticism -- I suspect that's an ongoing, and unfortunately, never-ending cycle of the online world... More and more people finding themselves frustrated with real life, trying to found an outlet or purpose through places such as this, but often doing so by being able to anonymously criticize anything they disagree with.
I believe I remember when you first came to CC, and you've been a staple here for a while. We would be sorry to see you go.
I don't know if this will help, but in the past year or so, I've been working on trying to connect with people individually whose posts I have read for a while and identify with rather than doing as much group talking in the threads.
Best wishes to you, and please keep in touch!
