They often leave out South Asians and sometimes Southeast Asians when it comes to discussions about Asians, which I find unfortunate. South Asians and Southeast Asians are very much part of it. Generally speaking, we all share similar values and traditions culturally. Even when we're in the West, there's parallelism in the ways we navigate life. We deal with similar issues. Whether or not we're Asian enough — just one example.
To answer your question, most westerners definitely still see him as an Asian person. Whenever I've seen western media talk about him, they've referred to his Asian identity. There are a few people who have edgy takes about this, but I think they might be projecting their own insecurities.
You mean insecurity to anything "white"? That's a bit depressing, I mean obviously I know there is a privilege in being of white race in the US, but the fact that one would let that be an enabler for them to blast anyone that even has a tinge of "whiteness", that's a bit sad.
