It "looks like" they have emotions because they have the same conscious experiences and emotions for the same evolutionary reasons as humans, who are their cousins on the tree of life. The reason a lot of "animal cruelty" is not banned is the same as for why slavery was not banned for centuries even though it "looked like" the enslaved classes have the same desires and experiences as other humans—humans can ignore any amount of evidence to continue to feel that they are good people doing good things and bear any amount of cognitive dissonance for their personal comfort. That fact is a lot scarier than any imagined harm that can come out "anthropomorphism".
