Most people – especially younger ones – have little experience with diverse people. They live in relatively homogenous towns and neighborhoods and usually relate to people who are fairly similar to themselves.
In online and casino poker games, you have to play with whomever sits down. You must compete against very different kinds of people: aggressive and passive, friendly and nasty, educated and uneducated, quiet and talkative, intelligent and stupid, emotionally controlled and uncontrolled, and so on.
You therefore learn how to understand and adjust to people who think and act very differently from you. The faster and better you do it, the better results you will get.

The government’s attempts to outlaw poker are based upon a misconception of its nature and value. It is not ‘just gambling’, and it should not be subject to the same rules and penalties as other gambling games. Instead, the government should allow you to play poker in regulated and taxed places because poker is good for you and good for America.
