The great thing is that you don't have to join any community. Python is my favorite language and ever since I got flamed for asking a technical question in their subreddit I stopped going there.
There are hardly any non-toxic programming communities out there. And if you value backward compatibility over everything else you can look at C and C++.
Java also has a pretty good compatibility story. I still use python for some applications, but it has created a lot of headaches, and also has the problem of being really slow. YMMV, but usually if you were to rewrite your c++ code in python, you would find that you need 10x as many servers (or likely more) to get the same performance.
