Questionable Patents

Should you really be able to patent such non specific ideas as using chat on the samescreen as you are watching your TV on? That it just what Microsoft did. Its not even a new idea, its not an invention specificly, its A GOD DAMNED FUCKING IDEA THAT HAS BEEN THOUGHT OF BEFORE!!! THE STUPIDITY OF THIS NATION IS ALMOST STUNNINING; THEN I REALISE WHO MY NEIGHBORS ARE.
