how do you scripturally defend the traditional doctrine of hell against annihilationism?

sven quoted:

And if thine eye may cause thee to stumble, cast it out; it is better for thee one-eyed to enter into the reign of God, than having two eyes, to be cast to the Gehenna of the fire - where their worm is not dying, and the fire is not being quenched (Young’s Literal Translation)

The way I see the text is this:
Jesus: "And if one of your members causes you to sin, get rid of it. Wouldn't it be better for 95% you to have eternal life, than for 100% of you to be cast into everlasting fire? Now I know most or all of you don't know what I mean by everlasting fire, after all none of the prophets of old taught you about it. But try to picture the fires at Gehenna burning night and day; worms crawling through the refuse picking on the dead bodies; smelling like your house after your mother-in-law comes to visit with her ten pet dogs and cats in tow. Pretty bad, huh? Now try to picture a place a thousand times worse than Gehenna--a thousand times bigger and a thousand times hotter. That's the place I don't want you to end up in for your disobedience. So I've given you a clear picture of what to expect if you die in your sin. Don't come crying to me on judgment day saying, 'But Lord I thought...' cause I'll say to you, 'Look, I warned you. Remember? Now depart from me--into those fires that I tried to make you understand by using images of Gehenna that you could relate to."

That's how I see that particular scripture--nothing more, nothing less.

Now there is much more I want to address in your link, sven and I will. Right now I have to run a few errands.

why the later? why imagine a place like that? might this be the reason for the common doctrine, to much imagination?

having no proper burial was horrible to the Jewish mind btw

Ecclesiastes 6:3

If a man beget an hundred children , and live many years, so that the days of his years be many, and his soul be not filled with good, and also that he have no burial; I say, that an untimely birth is better than he.
