I certainly don't think that you are dumb... just biased.
You write:
"IF THE DAMS KILL SO MANY SALMON AND STEELHEAD, THEY WOULD BE LONG GONE BY NOW".

In the Snake River, they are gone... for the most part. Wait ten more years of debate and study and delay... and they'll all be gone. And, chances are, with our wonderful fish agencies, you'll get your answer.

The large fish returns that you are referring to were hatchery plants... not wild stock (i.e. the kind of fish that spawn in real rivers). Do I have to wait 50 more years to see a large run of hatchery planted fish? I don't know if I've got that long.
