HSUS is feeling the sting of lessened donations. That's why they've been screaming about both HumaneWatch and the new Shelter organization. They actually issued a public statement about how THEIR donations were less because of the shelter group that says "Donate to your local shelters". This was one of their mistakes, since it made it more evident to the general public that HSUS doesn't support shelters, only their own pockets.
We do have to keep fighting them, unless you'd like to simply euthanize all your pets right now, roll over and give them your paycheck. HSUS won't be happy until we're all vegan without any pets or animal agriculture.
Give up, or fight? Easy choice for me.
