Honestly this was true for large parts of USAs history, but that hasn’t been the case for a while now.
In truth our democrat and republicans reps have almost no similar voting history, they vote the opposite of each other on almost every issue.
Below is a good visualization of what I mean. You can see that from the 50’s to the 80’s, there was really quite a bit of voting overlap by the parties, so during that period, you’d be right, both parties could be consider the same or similar.
But for the last 30 years or so, democrats and republicans have had very little overlap on what they vote in favor for. It’s party line votes on almost everything.
So how people can say “both parties are the same”, when they vote the opposite on almost everything is beyond me.
And that’s not even taking into account executive actions, like for example for the last 50 years or so every democrat president has provided contraceptives as part of foreign aid, and every republican has not.
We may not have options in terms of political parties to choose from, which I agree is bad, but saying both parties are the same is to be willfully blind.
So speaking as an American, the Indian diaspora here is typically thought of positively, at least in the sense they tend to be responsible members of the community.
Unfortunately, Americans are pretty geopolitically ignorant, and so end up developing views on countries based on the behavior of their American communities.
So I would say most Americans impression of India is “vaguely positive”. This notably includes at least tacit approval from American conservatives, in that Indians are left off their “which minority group are we targeting today” bingo card.
This is probably mutually reinforcing with America’s geopolitical priorities, which is essentially deepening ties with India as a counterbalance to China.
As to your “too proud of your country” comment, obviously as an American I sympathize, but they’re not wrong in that because of your country’s size and growth, India will become more prominent in global affairs.
Unfortunately as you’ve noticed, that leads to some people having an inflated view of themselves. It’s just something you have to live with as a world power.
Anyway, the below article actually answers your question, and overall, generally positive is the answer (but what did you guys do to South Africa though?)
