Rock Music Insult

I don't believe what I just read on my Google+ feed, Some plank recons that Jazz musicians play 3,000 chords to 3 people,and Rock musicians play 3 chords to 3,000 people, I am bloody furious, I am a Rock musician and have played a good lot of songs that have a lot more than 3 chords, This person evidently does not know a lot about music or he would not insult my intelligence and Rock Musicians like Brian May or Eric Clapton to name but a couple, So mate whoever you are learn to play a guitar and then think about what you said ! Pictures above  are Brian May, and Bennie King .
