Final answer:
Karl Marx believed that religion was a tool that maintained inequality and was not a means to unite the Bourgeoisie and Proletariat but rather a way to perpetuate the status quo, making the statement false.
Step-by-step explanation:
The view that Karl Marx's view of religion was the key to uniting the Bourgeoisie and the Proletariat is False. Marx believed that religion was a tool that maintained inequality within capitalist societies. According to Marx, religion reflected the social stratification and perpetuated the status quo by keeping the working class (Proletariat) in economic suffering, offering them the illusion of future happiness in an afterlife, thereby reducing the likelihood they would challenge their current economic conditions. Marx famously dubbed religion as "the opium of the people," suggesting it dulled the pain of oppression without solving the underlying causes of societal inequality.
