..and a real debugger > have you worked in Java before on a bad project and have scars My guess is that the opinion is just used as a way to signal their status as a 'pro' developer much in the same way people used to hate on PHP/Perl/VB/etc. endlessly. Ironically, this makes them look like amateurs posing as pro developers, as real pro developers demonstrate their status through their work, not their posts on social media.
