It's propaganda. It's the same reason why a large portion of Indians (even with full internet access...) are fervently pro-Putin in the context of the Ukraine-Russia war.
We're going a bit off topic here but I'll expand a bit.
If we both (presumably) start from the premise of "this invasion is a bad thing", then following this up with "anyone who supports it is just a moron duped my propaganda" and/or "the Russian administration are simply crazy" isn't helpful. This did not happen in isolation, it happened against a backdrop of decades of western failures in diplomacy & deterrence.
That's worth examining if we wish to prevent future wars.
I'm not an Indian, but I can understand why a country that was oppressed by the Great Britain for such a long time, and endured such atrocities, can opt to support the party that stands on the opposite side of Britain.
That alone could explain why not only India, but big parts of the worlds, especially the ones that suffered from the British and American imperialism, would rather see an arch-enemy of their usurper win against oppressors puppet state.
India was the chief non-aligned country of the Cold War, and for decades has warmer relations with the Russian Federation (and it's predecessor the USSR) than the west.
I understand this. I'm simply asserting that if one believes in this political drivel, ignoring the onslaught happening in Ukraine, then you've not progressed as a human much beyond the middle ages.
Unfortunately, it's how humans work. As a species, we did not progress beyond the Middle Ages. Our tech did, but we didn't. Still the same tribalism as before.
When we plunder the other village, take their crop and their wives, it's to bring justice to the world. When they come to us, take our crop and our wives, they are evil aggressors.
Nothing has changed, and probably will not change anytime soon. Thousands of years of evolution are still stronger than whatever thin layer of civilization we try to put on top.
90% world the world (i.e. nearly everybody outside the west) has a similar position on the Russia-Ukraine issue as India though. Is 90% of the world propagandized? Or can they have a legit different perspective on things?
Countries can have more complex positions than the simple "Ukraine good, destroy Russia" (or its inverse, "Russia good, invade Ukraine") dichotomy that many in the west go for. Many countries don't approve of Ukraine's invasion, but also don't like NATO very much and show some understanding for Russia's position.
Most countries wish to be neutral on this matter, continuing to trade with both Russia and the west, i.e. similar to India's position. Look at how many countries chose to sanction Russia. Of those who voted against Russia, most who chose to sanction are western countries. Very few Asian and African countries imposed sanctions. 87% of countries chose not to impose sanctions.
