You should take a stand with hands you might consider folding when you can't rebuy- you know he is

Well, here is a common situation.
I'm SB with KTs, it is folded to me. I raise 4*BB, He re-raise the pot(!) I re-re-raise, he goes all-in. He did that all the time! He Could have 32o or Ax. I wouldn't risk the whole tourney with a KTs.
What whould you(or anyone else) do here?

If he actually does this with 23o, why would you do anything other than call?

If you don't want him to put you all in, don't re-reraise him.
