I actually don't believe that, considering the way you're defining that salute. In fact, somebody mentioning it is a clear indicator to me that they're engaging in bad faith... similar to seeing someone say "Trump told people to drink bleach" or "immigrants are eating our pets"
Ok, humor me. Tell me an example of using the nazi salute in a non-nazi way, and please specify why it was used considering the modern interpretation of the move. Only modern use, not going back to Romans.
