Thanks for flagging the rayiner comment.
rayiner's original comment was defending colonialism.
"If it wasn’t for British colonialism, both of us would be subsistence farmers right now instead of on HN."
If you read his subsequent comment "forest/indoor plumbing" it is definitely sarcastic and comes off racist.
Further down he switches to India being older but does not consider that ancient Indian history is whitewashed in today's world in most western cultures.
