>Say you are someone who consistently spews out racist comments? as you are being downvoted, Well, it is not given that a racist comment will be downvoted, that will happen only if the community is non-racist, if it is the comment will be upvoted alright. On the other hand, you could put a test for joining, where the user will "prove" he/she is not racist. Besides being of course subject of every kind of cheating you can think of + 1, even if it worked fine, the result would be a strictly non-racist community (which only in theory is a good thing, in practice it will become an isolated community of think-alike). Of course you can replace racism with every other "debatable" argument in politics, behaviour, etc.
