I have seen 2 types of bashers. One which seems typical line of business app developers. They disparage other languages, praise theirs on basic things like IDEs, libs etc. I don't mind these much. However others who approach from position of authority like compiler hackers, language authors themselves, or very senior developers etc. Ideally criticism from them should be more valid but more often than not I have seen they keep making bad faith arguments and justify their hate by precise technical arguments so they can't be challenged by non-technical arguments. It makes vary of their arguments even on topics other than favorite programing language.
