We are a programmer s board, our topics define our virtual persona.

In other words we can't exclude anyone by real life attributes like sex or pigmentation inside this social system.

If you think this metaphor is too strong please replace it with a café and mobbing tea and mate drinkers.

The point is once you've decided to welcome these people you can't accept questioning them over and over again.

Otherwise you are sabotaging your own "decision" and insulting the clientele.
