SO nowadays, you really need to grab your paradox of tolerance, and ask youself, is the person preaching "openess" or "diversity" or whatever through the looking glass opinion or proposal or whatever will actuall increase overall diversity, or will it just arm a very loud, belligerent and agressive set of people that if it were reversed, wouldn't dare to do the same.

Of course it's not perfect, but there's a lot this world trying to use "tolerance" to ply people out of systems that are moving towards progressive diversity that necessarily must exclude a subsect of destructive vices.
