The thing that drew my comment was the word "enlightened", which we usually associate with being more tolerant, as you imply, and perhaps more tolerant than our parents were.
On the other hand, some prejudices seem to be more acceptable, including, among other things, prejudices against organised religion, or against people who hold certain opinions that don't coincide with the majority.
I've always thought that there are some people who love to hate, but are able to pick their targets so that their hatred won't lead to them being ostracised.
So if you are intolerant of racism, cruelty, exploitation, discrimination, inequality and so on you are not 'enlightened'.
the prejudices regarding 'organised religion' seem to come from amongst the cults themselves or between sects of the various cults. Not belonging to one of these organisations, and objecting to the way they conduct themselves and treat people is hardly prejudice, and if you want examples of 'loving to hate' then the conduct of these cults and the sects within them is as fertile as the garden of eden. Ever been to a rangers/celtic game? Ever been to Belfast or Glasgow in the marching season? They are celebrations of sectarian hatred. Watch out if you are a 'progressive' jew and you find yourself amongst fundamentalist, or you are the wrong kind of muslim.
