This clearly isn't true, I've never seen any public campaigns against "Hinduphobia" like I have with Islamophobia, at least here in the UK. Even liberals like to criticise Hinduism for it's caste system and oppression of minorities.
Pakistanis are just as annoying, I recall when they were pushing this idea that Pakistani cities are somehow safer and cleaner than Indian cities and about how Westerners should visit Pakistan instead, there was a subreddits called NoahGetTheBoat and a couple of years ago I remember Indians and Pakistanis flooding it to post weird news stories about each other's countries (of which there was no shortage of material) until the mods got tired and started tagging every single post related to India or Pakistan with "poo wars" after which it died down.
It goes back to the earlier point of South Asians pretending to be different from other South Asians, they will always bring up some edge cases like terrorism or scat rituals to try and defame their tribal enemies, not knowing that the outside world sees all of them as the same clannish, dirty and unintelligent people regardless of religion, caste or ethnicity.
KiwiFarms is probably the last place on the internet where you can vent about these people without feeling manipulated in that you are just making some other variety of South Asian happy by insulting his almost identical neighbour whom he hates for...reasons. 90% of the anti-Islam and anti-Indian pages on Twitter or Telegram are run by South Asians.
