I resonate with the first paragraph. Those people raised with beliefs of a time that does not exist anymore happen to be very conservative and refuse to see the change.
In fairness, for you to say those beliefs aren't valid now is equally conservative - things will change and maybe in the direction of their beliefs, in part because of what they do. That's how change happens - some people with a different vision persevere from being rejected to being accepted.
They are conservative about time X, and in your comment is conservative about time Y (which happens to be now).
And all change is always for the better, is always progress, some even say..
