So if by "plausible" you mean that, yes, you can imagine someone doing that, then you're right. If "plausible" means that you think it's justified, then that's another issue.
In this timeline, after a group of Hong Kong democracy activists planted bombs that killed a few hundred low-level people at the annual Chinese Communist Party meeting, China responded by announcing plans to bomb Hong Kong into rubble, rid themselves of the menace of democracy once and for all.
And then when they heard this, your country announced that they unconditionally supported China in this effort, and would supply them all the bombs they needed to take down these Electoral Terrorists, eliminate every last one who wasn't an enthusiastic proponent of single-Party rule. That local democracy advocates in your country had long been concerned with the Hong Kong situation, had long protested the government's inexplicable support for China in this matter, but were shouted down by every political party and called racists by a consensus that seemed to really be interested in using China to counter the prospect of Indian international ambitions. That watching the bombs drop, and watching your national media invite Chinese people on air for segment after segments, your democracy activists found in discussions online that they weren't actually some kind of radical fringe, that basically everyone outside the media+government was tired of the CCP and tired of our unending support for it.
There is a lot of nuance there, but what happened after Oct 7 is basically that Netanyahu & AIPAC, finally seeing an opportunity to answer the Gaza Question once and for all, jumped into their role as the villains in a pre-existing anti-semitic conspiracy theory, and proceeded to play the US like a puppet in order to effectuate a genocide.
I can have a nuanced view here; I can separate Jewishness and Zionism. I can talk to you about all the Jewish students at those protests who were holding signs supporting Palestine. I can note the extreme divergence between age cohorts within the Jewish community in the US, I can point out that the US is the largest Jewish population in the world (larger than Israel), who are coexisting perfectly well with gentiles, and that this isn't to Netanyahu's benefit at all. But these people constantly tell us that there is no separation there, that it is antisemitic to be against Greater Israel, that these concepts are one and the same. If that's the case, and you still disfavor genocide, there are Implications.
I can understand when some people misunderstand the situation; Antisemitism abroad is what Likud wants and needs to survive.
Hamas is not a pro democracy group. It's a radical jihadist group. Its mission is not to free Gaza, but to destroy Israel and kill all Jews. The people it killed on 10/7 were not low level government officials, they were civilians, including children. The method of killing was extremely brutal.
Moreover, Hamas is not some tiny group within Gaza. It is the elected government of Gaza.
You set up this whole false narrative that has no relation to reality. But I will tell you this: I know a Russian who is pro-Putin. I find his politics despicable. But I still treat him with courtesy and am willing to discuss things with him. I don't believe in cutting off people you disagree with. It's bad form and it doesn't serve to change anything. How much more so, someone whose politics I don't even know. Why would I make an assumption based on someone's national origin or race?
If you queried a hundred random people who knew this same Russian and were similarly opposed to his politics, do you believe that one hundred of them would share your perspective? Or would a handful give that guy dirty looks at the bar because they were not in the exact same headspace you are in?
I struggle with comparisons because I'm trying to illustrate for you what those people are seeing when they spontaneously start acting that way that is different from what you're seeing. It's difficult to find any comparable situation as lopsided as Israel's relationship with Palestine, and the almost inscrutable international response to that relationship. Liberal tolerance ethics takes deliberate effort (generalization is a natural cognitive bias), and all of the people who would typically provide guidance on normative ideals suddenly took on the unprecedented position that we should exterminate a couple million people in what is effectively a concentration camp because of a violent outburst against the people who put them there, that this was Good and Righteous Justice, that anybody who didn't want to exterminate them were dangerous fringe actors. People who rejected this propaganda storm found themselves ideologically adrift, latching on to whatever floats.
