Speak for yourself, but the exterminating Jews thing would have turned me off even as a small child. Please don't represent my tolerance for Nazis for me, and I won't represent your arguments for you.

Once again: If performance matters, then use PyPy or V8 or SpiderMonkey or ChakraCore or JavaScriptCore or Carakan or Nashorn of course.

It doesn't invalidate my argument that I used the name of the language Python instead of listing out every possible interpreter or VM that runs Python scripts, or every JavaScript VM, or every C++ compiler.

I've already said several times that Python is just an example. Did you not understand that part?

The hundreds of instructions difference between multiplying with CPython and PyPy still pales in comparison to the millions of instructions required to fork "bc".

And with bash you're still stuck with that terrible mish-mash syntax and converting back and forth between text and binary floating point numbers.
