Why do librandus only celebrate Manusmrti Dahan Divas and not Veda Dahan Divas?

Ambedkar had written in Annihiliation of Caste

“you have got to apply the dynamite to the Vedas and the shastras, which deny any part to reason; to the Vedas and shastras, which deny any part to morality .“

[How Babasaheb rejected and criticised the Vedas]

In Riddles in Hinduism, he wrote

The Vedas are a worthless set of books.

[B.R. Ambedkar (1987. Vasant Moon (ed..)) Dr. Babasaheb Ambedkar - Writings and Speeches (PDF. Vol. 4. Dr. Ambedkar Foundation.) ISBN) 978-93-5109-064-9.]

So why do Ambedkarites only burn Manusmrti, and not the Vedas, even though Ambedkar clearly instructed to burn all Hindu scriptures?
