> You're trying too hard to find suffering

I don't know how you can say this, frankly, unless you do not see or experience any of this suffering yourself. If not, you should be extremely grateful for your luck.

You don't have to try hard, at all, to find it.

> Most humans and most medium to large animals live pretty comfortable lives by default. It's easy and simple to draw a line where they're above the line.

How are you defining this, and again by which principle do you draw this line which isn't some ex post facto version of "well humans are here, so I'm going to say everything to the left of here"?

> I don't know if nervous tiny prey have consistently worse lives than lab treatment in the wild, but it's not an immediately outrageous claim

We should be extremely skeptical of this claim because it's so convenient.

It absolves us of the guilt for the tremendous harms we're causing them by proposing something which we would see as obviously absurd if it were applied to us:

"A short, miserable life of having all sorts of horrifying experiments performed on you in a lab is better than being free to live your life and die in the world at large." - Person who benefits from performing experiments on you in a lab

Sure, I'm skeptical of the claim.

But your attempts to equate it to the human experience are a waste of time. Nobody actually thinks humans (or cats, or bison) face the experience that SoftTalker was trying to describe. When we go by the actual intent of the statement, either it's true and mice but not humans face that, or it's false and neither mice nor humans face that. Any experience that you can say is the human default in full honesty, is not the experience SoftTalker was trying to convey.
