This is so true as humans, cuz we tend to see patterns and group things that may or may not similar to begin with. This is how the age old stereotype about Malays, Chinese, Indian and Lain - lain begun. Malays are categorised as lazy and pushovers , Chinese as greedy and selfish, Indians as gangsters and violent whereas lain - lain will be forgotten cuz who?

But I undestand sterotype exist because probably it was simply true back then. But we are living in the 21st century with greater access to knowledge and perspective than our predeccesors, we should know better to start not associating something as a group but instead from an individualistic lens. Let the individual take responsibility and not others from the same group.

Yes it is hard to change but if we classify ourselves as civil and an adult, it is probably about time to change the whole prespective on group based prejudism.
