Welcome to EvC Lakdar. We like to have moderators with a wide range of opinions. We generaly wait until we see how well someone can conduct themselves and show an understanding of the guidelines and spirit of the site before we consider them as a moderator.
We try to avoid banning (and even temporarily suspending) people. We prefer to explain to them how they could improve.
There is nothing stopping any poster from pointing out that the spirit of the site isn't being upheld. You can practice moderating by both setting a good example and making constructive suggestions.
