The ban on genetic engineering must be a pretty detailed document defining exactly what they mean, not just a simple statement that it isn't allowed. For instance, Spock was genetically engineered and I'm sure that could be said of any other hybrid people. That is allowed. And would they allow a bit of tweaking to eliminate naturally occurring birth defects?
I completely understand and agree with the ban on creating "genetic supermen" but realistically, where do they draw the line?
