A glaring omission
So where is SQL?
All I can suggest is that it simply isn't "trendy" enough for the people at Stack overflow to know, care or hate.
it also makes me wonder whether the "hate" is because a language is difficult to use to achieve the desired result, or due to some factor like unfashionable (i.e. not object-orientated), clunkiness or doesn't have a pretty editor.
My personal "hate" is for any language that resides wholly in an IDE - that doesn't have a printable form, cannot be written in a single file (even if it isn't generally done like that) or that enforces silly rules likeCapitalsInTheMiddleOfWords.
