Well, who says it's "not warranted?" I say it is.
Some people keep rats as "pets." Some people like to be tied up and whipped for "pleasure." They think "creepy" is "not warranted" then, too. You don't have to think it's creepy. In fact, it would be really creepy if you thought it was creepy and did it anyway.
But you can take my word for it, it's creepy. Or, if you prefer, "just a little off."
So rats are creepy? Mice? Crickets? What else? I am beginning to have the opinion that ‘creepy’ might be in your mirror.
What is a ‘little off’ is labelling ‘creepy’ based on ‘ignorance’.
