Whether I'm a programmer

if I use Lisp and call other languages "inferior" or do I need to accept Java and Python to be a truly faithful programmer?

Whom should I consult on this question of religion?

An idiot will use only one language. You may consider anything other than Lisp to be inferior, but Lisp won't be the right tool for the job every time.

And if anyone replies with LOL U CAN JUST MAKE A DSL PROBLEM SOLVED, then you've proven my point, faggots.

So to repeat what has been mentioned before, learn your Lisp (SBCL), pick up a scripting language (preferably Perl or Ruby, even though to many, Ruby is SLOW AS FUCK, but it has its uses), and learn a compiled language (C).
