That's my experience as well. However, I suspect a lot of it is not really understanding the situation, and not wanting to be bothered learning about it. In other words, I think it's possible those preferences could be changed with the right kind cultural or legal shifts. Even in my lifetime, I look at how massively public attitudes have changed around smoking, wearing seatbelts, and recycling, to take 3 examples. Each of those seemed equally immovable at one time.
