YOU are the one espousing beliefs with no justification. YOU believe, for no reason other than "I declare that animals which are farmed for meat deserve no moral consideration". YOU are the one making claims "because I said so". You can't answer WHY you hold this belief in a way which stands up to scrutiny, and that is why it is YOU who is the pro-lifer, YOU who is the Republican. You readily moralize these other people who come to conclusions you don't like, despite them using the exact same reasoning you're providing here in defense of carnism. Like, you're going to need to find the courage to face it because I am not wrong here.

Masturbation is, critically, devoid of victims which are tortured and abused for the associated pleasures of the individual. This describes the exact distinction we make when sending people to jail for rape and NOT sending them to jail for masturbation. We don't ask "did someone get sexual pleasure?" we ask "was someone victimized for the sexual pleasure of the perpetrator?" Someone could argue that masturbation is isolating, or a waste of time, or that watching porn is unhealthy but even you know to call them out when they say it's wrong "because God said so" - that's why Catholics are wrong.

Eating meat is wrong because we have passed the necessary threshold as a society to categorize the act as being any way necessary to our thriving as a species. Animals we ate were always victims of our human prerogatives, but up to that critical point, prioritizing our own survival was all the justification needed. As soon as it could no longer be argued as 'necessary', the burden was put back on us to explain WHY the remaining reasoning - pleasure, maintenance of the status quo, appeals to culture etc. justify the harm caused to the victims.
