The largest Hindu Sect in the US and a Sect linked to India's Prime Minister is accused of using forced labor to build temples in the US. (see New York Times 11/10/21). The case involves lots of US federal agencies for what could include violation of immigration and labor laws. Remembering that Hinduism does claim a caste system as core to its beliefs may permit what others might claim to be a conscious issue but does not reconcile what civil law requires in terms of how individuals may be treated.
This of course is the classic conundrum with a variety of faith practices where policy may conflict with practice and practice and policy may conflict with what is legal. It is worth noting that these conflicts have existed throughout the centuries with what many might decry as inhumane practices while the faith body might say it is core to the beliefs. The Crusades are a stellar example of where one faith practice (Roman Catholicism) viewed it as just to attempt to wipe out those who practiced the Muslim faith or where Pilgrims (the Congregationalists) sought to wipe out those who were Quakers - well you get the picture.
The bottom line of course is that much of what happens collective is driven by the leadership - self-appointed, elected or whatever. For faith practices - well, it varies on how leaders get to be leaders but the outcome is the same - most are voices of authority and guide - not unlike nonprofit boards. What I would hope is that the leaders only want to do what is best for their followers and those affected by their organizations. Failure to pursue this track should in my opinion result in minimally the removal of tax exempt status for why would the public want to give a free way to those who in some way or another do not give equal respect to all citizens.
