I am very new here and I am perplexed by the number of threads that get closed without explanation.

Is this a form of censorship?
Is this a Politically Correct Site?

Also there seems to be an inordinate amount of rules when I signed up. I thought the whole point of the internet was the free and open exchange of ideas and opinions. There seems to be an orthodoxy here that seems to stifle free thinking.

Please tell me i am wrong.
