Hmmmm. I must confess, I was unsure as to what "vacuous" meant. Here are a couple of definitions, which I think give a flavour (courtesy Webster's online dictionary):
1 : emptied of or lacking content
2 : marked by lack of ideas or intelligence : stupid, inane

Do yourself a favour, Mr Blah: don't go there, because you're not bright enough to call anybody (or anybody's ideas), stupid, not even Dodgy Dave.
And by the way, Blah, could you have Texture "spell out" when he's next going to "spell out" his policies, because I must have missed the last occasion he "spelt out" his policies - perhaps they were too complex for me to understand, or perhaps he's shit at spelling. Who knows?
