तब क्या हुआ जब कांवड़ियों से पूछी गई जाति, देखिए!/

Very true! What a disgusting reality! For those who shout "Jai Bhim" and even those who suffix "Laal Salaam"!
There is no alternative to Class Struggle, through unity of the working class and revolutionary struggle, to abolish capitalism, which is spreading ignorance , superstition, along with unemployment, poverty, inequality!
Casteism is adopted by the bourgeois class and being promoted, as can be seen here!!

Atheism vs religion

Religion is tool in hands of the capitalist class (or earlier classes before capitalism) to be-fool the working class, divide them and exploited them!
However religion, ignorance, superstition cannot be combated unless the material condition of the people (who are suffering from religiosity) is changed which makes them religious.
Few individuals and exceptions do become atheists but mass will not follow the scientific and logical path. They are "forced" to accept the unknown & non-existent god or any other forms due their life conditions, which is full of miseries and uncertainties due capitalism!
They are continuously indoctrinated into religiosity by their families, neighbors, religious & cultural leaders, schools & colleges, government departments, pillars of the bourgeois democracy, media & social media, films, etc.
Change the material conditions of the people, give them social security, like employment, quality & scientific education, free them from religious and reactionary ideologies and propaganda.
Then we will have a society, where atheism will become part of everyone and social environment!
And such a society, a society which is based on scientific and logical theories and justice, has to be a socialist society!
Work for socialism by combating capitalism and not few of the diseased symptoms of capitalism! that means, do not be part of reform-ism but revolution!
