So you attribute the golden era of Church influence, around the 12th century onwards, as the "not bad medieval era", yet the Church is somehow evil and not the new barbarian kings?

I never said the church was evil? Do you need help? You seem to be hallucinating a lot and making up random shit about strangers you know nothing about. And after throwing a casual glance at your comment history, that seems to be a common theme with you. Seeking help would likely be advisable.
