That concern, as I see it, is of a similar nature to those in the past who worried about giving the great unwashed the vote at all: or even wasting money educating them. The horrors it might bring. Yes I'd suspect there would be a number of things passed that future generations would look back on and shudder about, but that is democracy, the will of the majority. And a people do not mature until they are given the reigns to make their mistakes and learn from them. Eventually we'd learn not to always go for the short term easy option, that a nation needs to be realistic, and also to include minorities and not always override them for what the majority would like every time.
