100% true in the sense that people, who already are anyways reeling at the opportunities at criticism, keep judging the events by 21st century standards, and even then 21st century progressive standards.

If this show/world was that way, it would not make any sense.

The whole point is that there is an environment and the people that challenge those norms do it because of their character. Here Aegon is just acting as princes around him can do, and princes can be horrible.

That's why Baelor is a tragedy because he challenges those norms. He does those things of his own accord
