You're wrong.  You have refused to do your research, and you have been
ignoring information people provide to you.

You're wrong.  There are only two global *C* variables -- but all Python
objects are global.  Most people want to share information between
threads; as soon as that becomes a requirement, you run into *BIG*
problems with refcounting and garbage collection when you do free
threading.  That doesn't even count the problem I mentioned earlier
about interfacing with thread-unsafe libraries.

Now, would you care to learn how Python actually works before making
further pronouncements?
