If someone's preferred language/framework/environment doesn't have a good debugger, or if they simply don't know how to set it up, some percentage of them will start insisting that they don't even want one anyway.

This is the basic Sour Grapes concept.

Debugger is a tool, not a goal. I can reach a GOAL without debugger, using my software development skills only. I prefer to invest into quality of code, write more comments and documentation, perform refactoring, delete unused code, write test case to reproduce the bug, add more command line parameters, write better error messages with more data, and so on, than to invest time into a debugger. I'm the Software Developer, not a Software Debugger.
