I think taboos exist for very good reasons. The fact that something is a taboo does not, in and of itself, mean that it needs to be challenged. The problem is that very few people are rational. There are a lot of people who gain courage to do very unpleasant things once they've heard arguments that they can use as internal justifications, when they are not themselves sophisticated enough to understand how sound the arguments are.

I live in a poor area of London. Racism isn't an abstract taboo; it's a daily sight, and it's disturbing to hear the rationales some people come out with. It's clear they didn't come up with it themselves.

Basing your values on provably incorrect myths is building a house on the sand. Values must be fundamental and universal. They must be ends in themselves. They should not be based on trivia. They definitely should not be based on provably incorrect non-facts unless you plan on those values crumbling.

Good Value: All human beings deserve a basic, dignified standard of living regardless of their intelligence, who their parents are, or what their culture is like.

Stupid Value: All races deserve a basic standard of living because they have the same intelligence.

Fact: Jews score higher on intelligence tests than other races. Society widely agrees that intelligence tests measure intelligence. Therefore, Jews are more intelligent than other races.

If you base your values on stuff like "all races being the same" you are basing your values on non-truths and those values will crumble when faced with reality. Not all humans are the same. Not all cultures are the same. Not all biology is the same. Values should transcend petty questions about biology - they should be ethical value statements that recognize the value of all human life.

We should give minority groups fair treatment and a helping hand not because they "deserve" it but because it is fair and because we believe in the values of fairness and equal treatment for all human beings. Because we believe in the inherent value of human life - the sanctity of human life - and want to promote human life regardless of which culture it comes from, regardless of what biological quirks it displays.

I completely disagree with you. You might want whatever taboos you like, I'm ok with that and won't challenge them.

But heck, if you are going to discuss something then you must be free of taboos in that particular mater, or else your opinion is just bananas. I mean, of what value is your opinion on something you're afraid of talking about?

EDIT: I don't want to be a downvote bitch. But it I am noticing my comments on this thread are all downvoted. I guess some people has the taboo so strongly imprinted on their minds that they don't even want me to mention it.

A taboo is a means of enforcement of a group norm. I don't think supporting or opposing a taboo prevents you from having a valid opinion on the group norm itself.

For example, talking to children about sex with children is a major taboo. Supporting this taboo doesn't mean an opinion on the immorality of sex with children is automatically invalid.
