Different sets of neurons fire for different people on the same stimulus. Does that mean you don't feel pain in the same way another person feels pain?
That's an open question. But if we would assume that answer is "no", then all alive beings can "experience pain" because it' the same mechanism in all of them. Jellyfish can "feel the pain" if we will assume such answer, and I imagine a single boat travel cutting and tearing thousands of jellyfish will easily beat this whole lobster conundrum in the severity of the problem :)
PS: I'm not advocating for cruel behavior against animals. It's just that some questions don't have an easy clear answer at all, especially scaled to the planet level.
does one need to feel pain in the same way for it to be classified as pain. pain is pain. one of the things that unites us as humans is our ability to feel it and empathize with another.
if an animal can feel pain it doesn't matter if it is the same pain. Also I recall that Nirvana once sang "It's ok to eat fish because they don't have any feelings". For generations people thought that is true.
Some in my family call themselves Pescaterean because they for some reason don't want to inflict pain on animals (that look like us).
my point is pain is pain - the rest is just mental gymnastics that allow us to justify our own behavior.
