I think within our movement we so often forget we’re all working for the same things. There may be minor differences in the envisaged outcome, but basically the animal rights/vegan movement wants a world where animals are not being used or killed by humans.
The differences are about how to get to that situation. Having a clear and concrete objective doesn’t imply we also know how to make it a reality. On the contrary, sometimes having a clear objective can be misleading, in the sense that it makes us think the way to get there should just be based on our aim. If we want x, we ask for x. But that’s not necessarily the best, the easiest, the fastest way to arrive somewhere.

In the movie Lincoln, there’s a discussion between Abraham Lincoln and Thaddeus Stevens about how to pass the amendment for the abolition of slavery. Stevens talks about our “inner compass”, which should point North (showing where to go, what is right, etc), but in many people doesn’t. Lincoln’s reply goes like this:
“A compass, I learnt when I was surveying, it’ll… it’ll point you true North from where you’re standing, but it’s got no advice about the swamps and desert and chasm that you’ll encounter along the way. If in pursuit of your destination, you plunge ahead, heedless of obstacles, and achieve nothing more than to sink in a swamp… What’s the use of knowing True North?”
