I'm sure a proficient Java dev can be very productive, but it would take quite a lot longer to turn a Python dev into a productive Java dev than into a productive Go dev. I don't think this is controversial, but it's not really relevant to my point either way.

I'm really not sure about that. That said it seems you don't really want to discuss this further which is totally OK with me :-)
For others who wonder, my points are only that:
- I was a person who was strongly opinionated against Java and for Python and basically everything else (at that point I had been programming on and off for 10 years)
- Actually becoming productive with Java took a week and the big thing was culture.
