I guess it makes sense that a lot of people don't like pet hair... Sensory issues coule probably play a part for some people. Maybe you don't like the feel or smell of it?.. Or maybe just the way it looks? Allergies could cause a problem too.
I never really minded pet hair all that much, personally. There are certain kinds that make me sneezy or make my sinuses feel weird for some reaon, but other than that i don't mind the pet hair that's all over my house, lol. I love the feeling of pet hair when it's actually on the animal, though. The feel, smell, and everything of a dog is the best thing ever to me. So i think that's why i don't mind the shedding too much.
