Enforcing character traits is not forcing players to be a certain character, as there are a wide range of races. If you don't feel comfortable playing the fiercly loyal, very reserved in public race, you can play a different one.

I think it enhances rp to have clearly defined races, as not only does it add to the conflict/tension in the game, but helps in letting players become completely immersed in the world. IRL, we have many different cultures. Why would we not in game?

My question was more about the morals of the worlds and are there some IRL morals/values that we shouldn't break in game worlds?

The link, if you wish to check it out and judge based on more information, is and the game is Inferno: Classic.
