Why aren't you a vegan!?

Cards on the table, I'm not a vegan.

That said, it's very hard to argue against the common vegan. After all, almost nobody argues that there is some positive benefit toward the infliction of suffering on animals.

Nobody would argue in favour of collecting dogs in the back of a truck, and sending them off for slaughter in some local abatoir. But that's precisely what happens with the other sentient animals.

The process is often brutal, but even if it were pain-free, the argument goes that animals shouldn't be killed in the same way we wouldn't recommend it for horses or dogs.

I can't really think of a valid argument against veganism. You'd think, then, that I would convert to veganism, but I haven't - and won't. It's a purely selfish endeavour, then, because I'm being hypocritical about how I would react if I saw dogs treated in the same way as farmed animals.

True, there are evolutionary reasons for eating meat. I think the argument now is that there are sufficient plant alternatives.

So, why aren't you a vegan?

Perhaps you have a valid position I, or others here, haven't thought of.

But thus far, I can't frame a case against it.
