> Honestly I don't think anyone actually powerful nowadays cares one bit about "PIE" religions.

You obviously don't care about it, and I can see why any scholar of a Semite-based religion would want to suppress the connection, just as a Nazi would want to suppress the holocaust. To me it's a very big deal that the entirety of the PIE derivative religions were destroyed in Europe by the Semitic religious wave. I consider it nothing less than a major cultural massacre. What is weak to you is a big deal to someone else.

There is no "other side" here. The word derivations and the cultural commonalities speak for themselves. For the first time in history, we have an intelligence that knows all notable modern and historical languages. It knows their words and antecedents. This is more significant than any scholar.
