I'm an archaeologist so I do have some perspective on the long view of history.
Just wondering if normal people ever think about this?
There have been lots of times where plenty of people have signed up to ideas that we now see as manifestly wrong if not downright abhorrent.
Everything from Nazism, phernology, eugenics, racism to hitting your kids and drink driving, has had otherwise intelligent people campaigning to for them.
Does anyone here look at the modern world and ideas and take a guess how history will treat these ideas?
For a start, I think that homeopathy, plastic grass, how we treat ND people and cars for short trips will all be consigned to the historical scrap heap.
