I fail to see what the above has to do with prejudice, personally. Poor air quality is a problem in many parts of the world, notably so in developing areas.
The prejudice seems to be "ah India, nice try but you still fail badly in an unrelated area" while in fact in this regard Delhi is more progressive than much of Europe and the US.
Reducing plastic waste is a step in the right direction and should not be dismissed just because there are other problems that may be harder to fix right now.

That's not what a prejudice is. It's also not what he said. Maybe if people wouldn't be so hypersensitive we could address the problems a country might be facing. India has many issues.
So what if he points that out, while we're discussing a different issue? It's part of having a conversation.
Good points. Would we have the same conversation about the US though? "Electric cars taking over?" - "Wow but pollution due to fracking is a way bigger problem!"
While prejudice is not probably the correct interpretation, the GPs post reads like "don't ban plastic until air pollution is fixed". Any improvement is better than nothing.
