1. The "you" in a different universe wouldn't be the same "you." It'd be a completely different person. Even if the two copies have the same genes and everything, there'd be two separate consciousnesses.
Agreed, although there would be one universe in which everything happened EXACTLY as it did in the one in which you died, only in this universe you didnt die. You would still be the same person, only you died.

2. The many-worlds view of quantum mechanics is just one interpretation out of many. It's not been fully accepted, and I don't accept it.
The idea of multiple universes assumes that every time something happens, the universe in which it happens "splits", and in one of the new universes the event occurs, and in the others it occurs differently. Now, as far as I'm concerned, it is impossible for an event to occur any other way than the way it occurs. Every event is completly dependant on an event or events previous to it, and that each of these previous events are dependant on events previous to them, etc. And that an event can be traced back through an infinitly long series of previous events, on back to the big bang, and beyond. Therefore, there is no "chance" involved in anything, everything happens exactly as it happens, and cannot happen any differently in any other universe given the same circumstances.
Now, this is assuming that radioactive decay, an event which at this point in time there is no known cause, has a cause that we just havnt discovered yet. If there really isnt a cause for radioactive decay, and it really is random, then my argument is flawed, and multiple universes would be possible.

3. Consciousness, being solely the product of the interactions between a person's neurons (in my view), is bound by the neurons, which are bound to just one universe.
Well, it boils down to whether or not quarks are bound to a universe.

And isn't the two-slits experiment normally done with electrons?
No, it's done with a light source, and as we know light=photons.
