> I completely agree that colonialism didn't stop at 1947. I'm just saying that it seems like a cop-out to just use it as an excuse for all our problems.
I hardly, if ever, see people using it as a "cop out for all our problems", or people "shoveling all blame on colonialism". What I do see, though, is that this criticism is almost always made anytime someone makes mention of the actual continued effects of colonialism in the present day. It happens both on this thread and any other HN thread where the topic is brought up (though it's not limited to HN). In the aggregate, it becomes a way to dismiss these very real effects and ignore them altogether.
> Besides, I find it a bit disingenuous to put the full blame of a modern problem like pollution on colonialism, even when you account for continued influence way past 1947.
I don't (and neither would most postcolonial scholars), because the economic impact of 200+ years of outright exploitation takes more than 50 years to recover from. This aftermath of this economic destruction fundamentally changes the sorts of political and legal actions that are actually feasible (in practice). Even the US, the wealthiest country in the world[0], has outright refused to ratify the Kyoto protocol because of its effects on the economy[1]. In India, not only do you have to trade that off against the importance of economic growth in a developing economy, but also against the feasibility of actually implementing and enforcing policy changes[2].
> Do you see any Americans blaming slavery or legal discrimination for the current situation, or are they blaming the modern times?
Slavery and legal discrimination are responsible for the current state of the Black community in the US - that's the whole point. It's been 200 years and we still haven't been able to completely reverse its effects.
Incidentally, I do oftentimes see this same misguided criticism levied at the Black community, which essentially amounts to "you've had equal rights for 50 years now; it's up to you now to achieve success and end racial discrimination and inequality". While the situations are different (slavery vs. colonialism), this criticism is as misguided when applied to Black people in the US as it is when applied
[0] by raw GDP, and the wealthiest "large" country by GDP per capita
[1] ignore the political posturing in the rhetoric; this is very clearly the bottom-line reason
[2] Yes, inequality begets corruption and corruption begets inequality; it's a vicious cycle. This is why exploitative imperialism is so dangerous and exactly why fixing it is such a slow process.
