Ram Punyani is a carrer liar.
Here:
cow slaughtering is banned since the vedic age (ie atleast since 1500 BC)
yaḥ pauruṣeyeṇa kraviṣā samaṅkte yo aśveyena paśunāyātudhānaḥ,yo aghnyāyā bharati kṣīramaghne teṣāṃśīrṣāṇi harasāpi vṛśca - Rigveda
(The fiend who consumes flesh of cattle, with flesh of horses and of human bodies, Who slaughters the milk producing cow, O Agni, tear off the heads of such with fiery fury)
Do not kill the cow. Cow is innocent and aditi – that ought not to be cut into pieces. (Rigveda 8.101.15)
All of Beef eating instances in Vedas or otherwise is deliberate misinterpretations done by leftists to forward their agenda. It is very east to mistranslate sacrifice (which may mean many things) as slaughter.As the above shloka proves, even Rig Vedics reacted to slaughter of cows with homicidal fury.
And regarding rest of his rant, Shankara had almost zero role in making Buddhism disappear from India despite numerous internet warriors and others mentioning this countless time. By time Shankara was born, Buddhism was already marginalised except in Bengal and in Bengal it was Vaishnavism which dislodged Buddhism in 11th century not Advait.
However, kumarila bhatta (someone our carrer liar Ram Punyani does not know) did play a role in marginalizing Buddhism. In fact, Buddhist scriptures and inscriptions confess this fact.He defeated the Buddhists in numerous debates all over India and converted many kings back.I am quoting Buddhist historian Taranatha verbatim where he testifies that Kumarila Bhatta defeated many buddhist monks . Since Buddhists don't fabricate stories of their own defeat, I assumed this story to be true.The king was not named but he was said to be the ruler of Dramila country.
Regarding Pushymitra Sunga, again a strawman.The damage he did to Buddhist shrines was reapaired by Pushyamitra's sons, and some mild episodes of persecution were not unknown. Ashoka put a bounty on head of Jain monks because they drew Buddha sitting at feet of Mahavira. These instances does not flared up into full blown genocides because Indians does not has bloodlust seen in Desert cults.
Another somersault done by our carrer liar Ram Punyani is that on one hand he states that Buddha prohibited slaughter of cattles and on other hand he states that he readilt ate beef.
The logical fallacy of this should be evident to even a blind. Buddhism, since it's inception was always more permissive on foods that could be consumed. It never brought in culiniary taboos in Hinduism.
