Okay, since you insist.
I'm not racist. I don't care about race. I do care about culture a lot. By culture I mean a set of "default behaviors" and values that people from said culture are more likely to exhibit. That's where my issues with Indians began and continue. Of course you are right that generalizing over 1+ billion people is a futile exercise. Intellectually, I agree. And yet, in my personal experience, certain behaviors and attitudes they have just keep coming up with frequency, that just doesn't match any other group of people I have been interacting with. I live a rather international life. I interact with people from many, many cultures. I currently live in a culture, that is completely alien to my own, and I love it. It's not a problem of closed mind or some kind of supremacy thinking. I am free from that.
Specifically about Indians - I find that great many of them prefer memorizing over thinking. In the IT consulting days of my career, I noticed that they seemed to have 4-5 solutions, that they would apply to all problems. Whether the solution would fit the problem or solve it, was secondary. If it did, great. If it didn't, well that was someone else's problem. Half of my job was fixing stuff that an Indian "fixed" before me. The appearance of having fixed something was much more important than the actual fixing. It was all about appearances with them. While people in general seek recognition, I have never met another group of people who are so eager to lie and cover things up to gain some perception of short-term bump in status. It's not isolated to work environment. You see, I suspected myself of perhaps being racist in the end, so I would challenge myself to befriend Indians if I met any - just to see. Maybe I was being judgmental and wrong? The last time I tried it, the Indian man I met kept kissing my ass so much I had to cut him off. Why did he do that? Based on what he was saying, he saw me as someone from an "upper caste" (he projected his ideals of a successful businessman on me) and desperately wanted me to know how much I have done for him (I haven't done anything other than having a few conversations about life and business in general). Took me a while to understand that all this excessive praise and ass kissing was an attempt to elevate himself by proximity to something great. Needless to say I am nowhere as great as he portrayed me to be. Later I also found that half the stuff he shared with me was made up to impress me.
Another feature of their culture is extreme pride. They will never stop talking about India, Indian culture, Indian food, etc. They expect you to praise it, be in awe. If you aren't, they will pressure you to change your mind. Since working with them was a universally appalling experience, I wasn't impressed, so that came up a lot. You see this pride and attention seeking everywhere online. A normal person will say "Hello", "Good morning". An Indian will say "Good morning FROM INDIA". It must be mentioned, because it must be noticed and praised. It's just tiring. There is a reason why so many are waiting for country-based filters on Twitter. You wouldn't have guessed which countries are most upset about this.
I am certain that there are reasons and explanations for all of this and that there are many exceptions. As you have mentioned, there are so many of them, they can't all be like that. And fair enough. I just find all of this so tiring, that I don't want to deal with them at all. If 1 out of a 100 is a smart and pleasant person, they are still surrounded by 99 that I don't want to deal with. It might be sad, but it is what it is.
