There are Hindu nationalists (mostly uneducated, and idiotic people) who engage in violence against Muslims. Then again, these incels will engage in violence against Hindus and Christians as well, for any cultural issue they have. They are the Indian equivalent of the people below.

Then there is terrorism from Pakistan over Kashmir. However, I have not met a single Pakistani or an Indian who actually hates each other. Pakistanis are exceedingly polite and nice to Indians, and so are we. It is more a government and media conflict than a people conflict or bad blood.
Also, apart from the idiots I mentioned above, if you go to India you will often times see a Mosque, a Temple and a Church all on the same street. I was raised Catholic, but I have been to Mosques with my Muslim friends. Our Hindu and Muslim family friends have come with us to Christian pilgrimage places many times. Heck, my neighbors growing up in India were Muslims and I used to routinely jump on the guy's back when he was doing his Namaz and they'd still treat me as their kid. At one point I even asked him to teach me to read Arabic and he did lol.
India is complex and contradicting. You can either choose to actually learn about it, or resort to a simplistic understanding of what you think India is based on some media narrative.
