For some context, this was a :reddit-logo: thread talking about old dnd settings and whether or not they should bring Kara-Tur back. There were plenty of shitty racist takes in the thread, but comparing the existence of christianity in europe to the brutality that african/asian/south american countries experienced during colonialism seemed especially bad.
Actually, we don't ignore Roman colonialism at all. Celebrating survival from Roman colonialism is the basis for multiple Jewish holidays.
So, in conclusion, colonialism has actually always been bad.
Yeah most of the celts basically didn't survive it, it's something to be proud of
