I am sorry but Pakistani/indians on here are so weird?

There was an Omani man on here from the UK who wasn’t interested in south Asian women except Bangladeshi. The Pakistani and Indian accounts started to get upset by this. Also accusing him of lying about his race. He confirmed he’s Omani but they still couldn’t accept that he liked Bangladeshi women?

I have seen this attitude toward Bangladeshi in the UK by Indians and Pakistanis. What is the reason

Pakistanis claim they’re better looking because apparently the think they alook white but tbh they just look south Asian so I dont understand how they look down on Bangladeshis

(I am russian btw with lots of Bengali friends)
