Is this a recent phenomenon? It seems like everyone who has a dog that wasn't bought from a breeder feels the need rub their virtue in others' faces every single time they mention the darned mongrel. "My poodle Henry -he's a two year old rescue - loves cheese!" It's like veganism but with dogs. Don't they realise how sanctimonious they sound?
What the fuck is wrong with you? 
You have a problem with people who have homed an abandoned animal, AND you hate vegans too? 
Bet you hate Christmas, The Simpsons, Friends, The Royal family, snow, people holding hands, and Valentines Day too eh? And you must fucking LOATHE kittens and babies, and you probably eat dolphin on toast.
Urgh, merry fucking Christmas misery guts! 
Oh, and I have had 3 cats in my lifetime (two still alive,) and they were all rescue ones. I am proud of giving them a lovely home with lovely me and my lovely family. If that bothers you, you spin on the end of my fucking finger.
