This is also disingenuous, they made him an avatar of Vishnu to subvert Buddhism in the country... if you look into the means of this you learn that his role is to mislead atheists/unbelievers so in no way is he looked upon in a positive light.
Of course most would argue for Balarama in his place anyway because they want nothing to do with Buddha.
Well, the SriVaishnavas may say so, not most Hindus. Even Jayadeva in 12th Century in his composition "Dashavatara" said this of Buddha:
"nindasi yajna-vidher ahahasruti-jatam
sadaya-hridayadarsita-pasu-ghatam
kesava dhrita-buddha-sarira jayajagadisa hare"
(O Kesava! O Lord of the universe! O Lord Hari, who have assumed the form of Buddha! All glories to You!
O Buddha of compassionate heart, you decry the slaughtering of poor animals performed according to the rules
of Vedic sacrifice.)
Sri Dasavatara Stotra, verse 9
We did not come up with the idea yesterday.
"According to Doniger, "Hindus came to regard the Buddha as an avatar of Vishnu between A.D. 450 and the sixth century," first appearing in the
Vishnu Purana (400-500 CE).
The Buddha is mentioned as an avatar of Vishnu in the Puranas and the epics such as:
Harivamsa (1.41)
Vishnu Purana (3.18)
Bhagavata Purana (1.3.24, 2.7.37, 11.4.22)
[web 1]
Garuda Purana (1.1, 2.30.37, 3.15.26)
Agni Purana (16, 49.8)
Naradiya Purana (2.72)
Linga Purana (1.71)
Padma Purana (3.252)
[20]
Skanda Purana"

We have hundreds of thousands of Buddhas, Gutamas, Siddhartha, Tathagatas, Amitabhas, Maitreyas, etc. among us (including my son, who is an Amitabha, not named after the actor, but after my guru Gautama, the Buddha).
Can you ban Hindus from revering, worshiping Buddha, if they want to do so? "Gautama Buddha in Hinduism" in Wikipedia has images of ancient temples and paintings depicting Buddha as an avatara of Lord Vishnu. And where did the persecuted Buddhist go to? The Chakmas and the Tibetans came to India and were happily accepted, even the displaced Buddhists from Myanmar because of persecution by military rulers.
