"There’s a benefit for white-nationalist groups who are anti-Islam to align with this group of Hindus – having non-white allies can soften their image. On the flip side, Hindu nationalists may be able to push their own agendas more effectively when they find common cause with other groups, Professor Subramanian says."

The white nationalist scene is more nuanced than has been portrayed by Subramanian. Read a few books on the KKK and hate groups like Stormfront. The vast majority of them supposedly believe in "the enemy of my enemy is my friend." The white nationalist groups antagonize Israel and Jews. They grudgingly support Islam, under the belief that Islam is the enemy of all Jews.

At the same time, white nationalist groups would love to support Hindu nationalists, especially those who live by the caste system. The normalization of caste based division is something the white nationalists love, and that such a theme can be found in contemporary Hinduism is a boon for them.
