That is what is happening with @Zurrrrr guy. In fact, he is not questioning. He is just implying inefficiency and opinionating on inferior problem solving skills of India on things he won't cite his research on. That is what makes it racist.
When US was cross questioned about cost benefit analysis and comparative budge analysis, it was promptly done so by NGOs and UN backing up with how that strategy is flawed. But US was hell bent on prestige of being first in space and that reply was apparent and open to criticism.
There was no deeper prodding/questioning into the specifics or support of arguments by @Zurrrrr here. There was just a quick judgmental attitude which made me claim prejudice in him. I urge you read his comment again.
Making someone specifically racist comment is not the bar to judge. Why would someone educated make it so blatant in 2023? Racists will always incorporate euphemisms and innuendos among many other tools to crystallize their thought of racism.
The US space programme has been questioned in almost exactly the same terms since its inception, without any hint of a racist motive. If it’s reasonable to expect NASA to justify its existence on a cost benefit basis, I think it’s reasonable to question any space programme on that basis. I don't think it’s reasonable to infer racism in this case when there was no specifically racist content in the comment.
If we’re going to convert skeptics into supporters, the way to do that is respectful reasoned argument, not impugning their motives for even asking the question.
