Juan summarized it very well.
“Well, either human rights are above imaginary ‘animal rights’ or not.”
So, a possitive right to abuse other for your own benefit is a ‘right’, the best and most powerfull one, a ‘natural one’, while the right to not being enslaved, tortured and murdered is ‘an imaginary right’.
You are a socialist, you just use animals instead of citizens, you defend ‘possitive rights’ for 'the well being of x.. in this case ‘humanity’, for the ‘general interest’, because ‘they do not have innate rights, only the ones we give them’. You are a tyrant, you just don’t attack those in your same group, you go after the weaker ones.
So, its bad to tax citizens and kidnapd them for military servitude because that would be an initiation of force, and would stop them for pursuing their own goals, but you can use force to kidnap an ape and experiment against it constantly using force and stoping his own life and his ability to pursue his goals.
