Rants...rants. Well if I were to rant about the English language, I would go for something that has to do with unconventional pronunciation/spelling of certain words - Why does "x" have to sound like "z"? Why can't things be simply pronounced just like they're spelled? I can't stand silent e's!!
Or you could go for something like, "Why is it that the English language needs to adopt so many foreign words and terms? Why do we need the word 'ciche' when we can just say 'uptown' or 'hors de ouvres' when we can just say 'appetizer?' I mean 'uptown' and 'appetizer' are ENGLISH words. So let's stick with our own language here!!"
