People who anthropomorphize their pets. Washington state ferries are now allowing dogs to ride on the passenger deck, and all the Fur-Parents are coming out of the woodwork denigrating toddlers and children while saying their precious fue-baby is far better behaved and deserves equal, if not greater, rights than those children.
My parents to this to their dog too, and have on numerous occasions prioritized the comfort of their dog over spending time with their grandchildren (E.g. bringing the dog on family vacations and then not attending outings with their young grandchildren (who they do not see often) because they cannot leave the dog home alone (they can, its old and just sleeps all day and would have no idea they left for a couple hours). It would be one thing if everyone loved the dog, but this dog has no personality, is slothlike, and the only people in the family who are warmer than nuetral on it are my parents.
I am not articulate enough to put the reason into words well, but when people denigrate children and act as though children are a huge, unneccessary burden on others in a public space it really annoys me. ESPECIALLY when they follow it up with a comparison to their angelic fur-baby.
