I think it's probably the worst language I've had the misfortune of having to write anything in. Certainly it was the one I enjoyed the least (even slightly less than Fortran 90 which was somewhat of an achievement), and I think it wins my "most hated language" because of the intersection of awfulness and the nonzero chance that I'd have to program in it. While there are almost certainly worse languages - COBOL certainly appears to be one - there's effectively zero chance that I'll ever write anything in them, hence they're more of an amusing curiosity than something I can hate. Whereas I've had to spend interminable days on XSLT in the past and unfortunately I can't say for sure that I'll never have to again.
I would at least like to claim that it wasn't blind hate; I have used XSLT before so it's partially sighted at least. And really, it's tongue in cheek. XSLT is a programming language, "hate" for such a thing only really goes as far as "I don't like working with it and hope I don't have to again".
Right. For our purposes, you no more need an argument to hate XSLT than you need one to hate chocolate. You tried it and didn't like it. Case closed. ;)
