Assuming you're against it because you're of the opinion that 'hacker' means 'bad guy', try reading up on the subject .. (yeah, all links from ESR, such is life).
Blech. That's not how natural languages work. Words don't get
defined and then never change meaning. New words are created
every day. Words fall in disuse all the time. Words change
meaning, or get a new meaning next to the old one. Dictionaries describe current and historic usage -
the evolution of a language, they don't
lead the way.
For many people "hacker" means "bad guy". Regardless how
much ESR writes, that means that (the|a) meaning of "hacker"
is what "cracker" means as well.
