Because everything sounds fancier in Latin and we are the heirs to the older more noble tradition unlike the nihilists in the puppy kickers. For those who don’t speak Latin (I don’t, a very nice and anonymous Latin scholar helped me with it), ADFERTOTE PLUS CATULI means BRING MORE PUPPIES! and is pronounced “odd-fairt-Ohte ploos cahtooly” (Where the capital O is like the o in clover).
And why not Sad or Rabid Puppies, but just Puppies? I think this year clearly demonstrated we are all have the same enemy and will be treated as such regardless so why not unite?
