pros

Lets say what we like about programming languages for a change.

C: Very fast and simple syntax.
C++: Has some useful standard libraries that C doesn't have, like vector and map.
Java: Has a very good garbage collector.
Lisp: You can make intersting self-modifying programs with macros.
PHP: Is one of the more readable scripting languages
Python: The forced indentation of code is an interesting idea
Ruby: no comment

Lisp: You can make intersting self-modifying programs with macros.
If this is the best “pro” you can think of for Lisp, you don't know it well enough to be commenting on it.

Of course, it's not likely you know the others well enough to comment either.
