Is it your opinion that it is better to spend resources in ignorance, possibly harming, helping, or doing nothing, than to allocate them meaningfully with full knowledge?
No, of course not. Your implication that this knowledge of genetics could somehow help allocate resources provides a very clear example of my concern. While you may be thoughtful and evenhanded, many people in power are thoughtless and greedy. Others still are racist and sexist.
You haven't demonstrated at all why ignorance will stop people from being racist or sexist or thoughtless, so you haven't made the case you seem to think you have.
