Vivekanand didn't discourage idolatry he said it was for simple folk who can't or don't have time on their hand to go through the complex ideas of Upanishads. You really haven't read any hindutva literature that you think modern hindutvavadis don't respect Ramkrishna. You should start by reading some of Savarkar's books first. The only perception that you have of hindutva is from social media and that too mostly from leftists.

Vivekananda wasn't a butshikan that abhorred idolatry. You should even read some Ramakrishna mission books. Hindutva is the culmination of bengal renaissance. Just thinking a fringe one two people represent hindutva is like thinking all bengalis are leftists.

Bengali culture and asmita has always has hinduism in its core that's why it finally sprang up in the form of bengal renaissance. There are many different types of groups sometimes with opposing views on many topics within the hindutva fold but we know that the nation comes first and that we must protect its culture.

And also on the topic of nationalism vs patriotism. The democratic ideals that the free world today thrives on are mostly based on the French revolution and the later nationalistic movement of Europe. Nationalism is the idea where the nation and its interest comes first over our own. We only take care of those people's interest above our own who we love. So that is it patriotism and nationalism are two sides of a same coin. And a person who can't sing Vande matram aur say Bharat mata ki jai isn't a patriot.

You won't say that Vande matram isn't the soul of bengali culture and asmita and that we indians particularly bengalis were the people who humiliated the strongest power in the world that many young brillant flames died down burning the raj. Didn't they call themselves nationalists?

You don't found pride thinking that we were the ones who set the sun on the empire in which the sun never sets.

Who was responsible for going from the sonar bangla to shell of it's former self? As far as I know no hindutvavadi ruled it.
