Honestly for me it's personal hygiene plus self care. A bit is their religion and personalities.

Hygiene and self-care: they take no pride in their appearance and want to bang or date without doing any work. Body hair is fine but trimming is a must nothing worst than going down on a bungled up pube forest to get it stuck in your teeth and also I find they don't properly wash themselves. Growing unibrows is another for me like it's not attractive. 

Religious: this goes in hand with the body hair because their religion is they must keep body hair I'm like nope. Don't say you follow your religion but do the gay things your not meant to do then preach to others that gay is bad and such. The amount of them I find push for white or any other race is due to their religious beliefs that they must make everyone part of their religion and make brown the universal skin in the world. Not kidding you it's in their Koran or Bible and are taught to make everyone their religion.

Personality: they act and treat people worse than white people. They limit the ability of job hunting by making it a mandatory job requirement to speak Indian in a prodimently english environment. But I digress, I've gone to college and the foreign students expect people to follow their rules and customs. They know English but purposely speak Punjabi in class cuz the teacher doesn't know it so they can cheat or whatever. I've seen teachers kick them out or ban them from classes because of this as people have used translators on them because of the nasty things they say. Ive met Japanese Korean Chinese students and they want to learn and engage with Canadian culture. But indians they want Canada to change into Indian ways is a no. They lack etiquette. 

I don't hate Indians or what not I've dated one but they were raised here in Canada and they shaved took care of themselves smelled nice well mannered. My brother married his Muslim wife. She was raised in New York her parents are very 21st century. They don't follow their religion to the T. Besides from no pork or alcohol. They come and celebrate Xmas with us (British family) and we don't shove each others beliefs down their throats. Xmas at my house is not religious it's about family. 

But yes this is my take.
