C++ is the only language I need?

I've been looking to learn programming (technically I did a little Pascal in high school) to program some small video games. The thing is, every time I look at programming languages to use, it keeps coming back to C++. Java is too slow, Python is too slow, C# is for fags, nobody uses Delphi, etc.

Is C++ really the only good language for video games?
Is there anything C++ SHOULDN'T be used for? From what I've seen, C++ is recommended for everything, and all other languages are just for amateurs, very specific platforms, etc.
