I guess all those things are worse than your pet getting West Nile disease, rabies, distemper, or any of the various diseases pets can get.
Some horse people have stopped giving their horses vaccines because " Wild horses don't need them"(wild horses don't live as long dumbfuck) and west nile is going rampant. Seeing a horse with west Nile so bad they need to be euthanized is not something I'd wish on anyone. It goes neurological in them and causes loss of coordination and seizures.
I'm pretty sure women don't want to date people who have any sort of disposition that leans towards hating them or believing that women are lesser than men.
Unfortunately, a lot of men learned that way of thinking early in life(from family and/or media) and it ruins any attempt at a relationship, then they blame women and run to the very people who set them up to fail for validation, or find new ones like that sex trafficker with the pizza boxes, or that canadian psychologist who sugar coats sexism online. Repeat ad nauseum.
