The basic issue is that in Mar 2017 the BJP mayor of Meerut started a practice of singing Vande Mataram before Meerut Municipal Board meetings. As a result 7 Muslim members refused and walked out while it was played. Harikant Ahluwalia the then BJP mayor of Meerut refused to let them back in with taunts made to these councillors like "Sing Vande Mataram or Quit India". He proposed that membershp of those who refused to sing Vande Mataram be terminated.
It is clear, at least to the people of Meerut, that BJP's actions were illegal, political and communal and they elected a BSP municipal board.
Faced with this public slap by a lesser elected representative, Naidu reverted to his political animal self and made that outrageous statement designed to imply that Indian Muslims who refuse to sing Vande Mataram are anti-national. Who was Naidu referring to when he said "If not the mother, who would you salute, Afzal Guru," if not to Indian Muslims ?
Needless to say our (dis)honourably still political Vice President made this statement against a backdrop of some calendar art image of a so-called Bharat Mata holding an RSS dhwaja in her hand.

Leaving aside the propriety of Mr Naidu making televised statements from a private RSS function with such a backdrop, I fault Mr. Naidu for not knowing enough Bengali to know from Bankim's AnandMath that Bharat Mata has 10 limbs and not 2.
The actions of the BJP in Meerut were clearly illegal. Nobody can be forced to sing either the national anthem or the so-called national song. There is no law which makes singing of any song compulsory. Thiat such compulsory singing is unconstitutional is already decided by SC in the Jehovah Witness students case.
Similarly, there is no law which makes singing praise of worshipping idols and images (especially in temples) compulsory. Nobody can deny that the worship of idols of Hindu goddess originating from modern Bangladesh in Hindu temples is specifically praised in the later verses of Vande Mataram.
हृदये तुमि मा भक्ति,
तोमारई प्रतिमा गडी मन्दिरे-मन्दिरे।
त्वम् हि दुर्गा दशप्रहरणधारिणी
कमला कमलदलविहारिणी
वाणी विद्यादायिनी,
Mr. Naidu has greatly disrespected his Vice Presidential office by indulging in cheap politics unbecoming of his Constitutional post. This is what happens when party hacks are rewarded with such retirement postings at public expense..
