What it has anything to do with insecurity? I personally don't get when people having pride in something which they got stuck with without any choice? I neither have any sense of superiority or inferiority because of my caste, ethnicity, culture or religion. Pride should only come from one source which is your personal achievement. It should not extend beyond yourself and you certainly should not feel pride for happening to be born of a certain race/ethnicity (or in a certain country) because you played no part in establishing that outcome.
The more you think about race, the more you become a racist. People should be classified by their character and achievement instead of their race or ethnicity. Race/ethnicity is nothing more than a pointless physical attribute just like the size of your feet or the length of your thumbs. Your race or heritage or nationality or color or ancestry or ethnicity or blood or descent or genealogy or lineage or origin or pedigree or whatever else you want to call it does not define you even if you want it to. Only your actions, your thoughts, your character, your choices, your achievements, your failures and your current life can define you
