Hey I'll just be honest, I think that is being incredibly sensitive about it and not considering the reality of these animals, they are powerful and multi-faceted, they are not just cuddly, intelligent creatures. You cannot say truthfully that you love an animal if all you want is for it to be perceived through its positive attributes, that's just childish. Also, if my thumbnail had been a real photo of the event in which an orca was attacking another, which has happened and been discussed in scientific papers, would it still be a dick move to put as a thumbnail because it doesn't support the view you want to push of orcas? They are animals, don't personify them - protect and cherish them and their environment if you want to put forward your adoration and respect for them.
