Why actions of few Indians in India or elsewhere are attributed to all Indians?

I haven't seen that the entire country is blamed or attributed the culpability of a few who decided to do wrong. Example, 1. 2-3 years ago one Indian randomly crossed the line and imposed himself on a Korean vlogger girl in Korea. 2. Few of the Japanese bars don't allow Indians and the same goes with Korean bars as well because few Pakistanis misbehaved with dancers in the bar and Bar owners said that they can't distinguish between Pakistanis and Indians and Bangladeshis. etc. etc. If you search for white people misbehaving with Singaporean girls you will find a couple of videos and this happens there on a daily basis as I have seen firsthand. \> But they are treated differently than us, why? Because of skin color? Because of economic status? Because of first impression that we go there to take up jobs where white people are invited to take up jobs? Actually, application procession and hustle for both races are the same with different perks. Why there is systematic hate against Indians and that too specifically men? Is China or the USA investing money? Because lots and lots of Pakistanis and Indonesians are involved in online hate against Indians they actively put hate posts against Indian and Hindu culture. If you don't know then according to the American expert Henry Kissinger, the countries that are under the USA's help (Allies) like Israel, Japan, South Korea, etc. are their extended dominion and those who is their friends are actually getting more backstabs to convert them into their allies e.g. India, etc.
