Out of purely academic interest, how are you not bothered by the clear contradictions in that logic?
> we ultimately need to end animal testing
and,
> work hard to eliminate animal testing
One is known as a universal; animal testing shouldn't be done regardless of the consequence. The other is a much weaker standpoint. You've taken the extreme condition of "cheeseburger" where most people would say there doesn't exist anyone who can't reasonably switch to a non-animal product - but what about cosmetic products which people use to help their self-confidence (acne treatments and what not), can those be tested on animals?
By what metric do you choose what's necessary and what's not in the meantime? Your own example of leather boots isn't directly survival related i.e. you don't die if you don't have them.
The final problem is that it's not an unreasonable hypothesis that there will be products which will always be needed to be tested on animals (such as medicines) - is it morally correct in your worldview that we continue to pursue such products?
