Cruelty looks adorable... I am so confused! (I only joke, cruelty of any kind from any species is bad. Also Dolphins are highly intelligent creatures, so it does not surprise me there would be a few asshole dolphins out there... asshole fish mammal thing...)
Fluttershy wouldn't hate a species of animal based on the actions of some individuals. It's not like dolphins are the only mammals with the stereotype of the males being violent rapist-murderers. Lions and bears have that too.
Edit: Wait, I forgot about the thing with the dragons....
I realize that taxes are a crucial part of any functioning society. I'm saying that it costs less to put homeless in homes than it does to have the tax payers provide for them to a limited degree, etc. Besides, I really just want the dolphins gone. Well that and there's no Jesse Venura pony (that we know of).
