Is it ironic that...

Goldfish live in glass houses, and all we give them are stones? I had made a meme pic with the idea that goldfish, being the last critter one would expect to throw stones, would be given so many of them, and also live in a glass house. I have rec'd several comments telling me this is not a proper irony. http://memebase.com/2012/07/13/internet-memes-people-in-glass-houses-shouldnt-throw-stones/
