Parents should discipline their children, not teachers.

Unless they have a *very* good reason, parents should never discipline teachers. That should be left up to the school's administration.

also, "than" not "then", "their" not "there" and your basic comparison compares quantities that are not on the same scale.

("That's bigger than it cost!" uh... what?)

Personally I think parents should discipline teachers when the occasion calls for it.

You left out "responsibility" and "amount".

those are misspellings of a sort i have no room to complain about. then/than and their/there/they're are both of the category of stuff that spellcheckers won't catch and that I therefore treat as grammatical errors even though they could be simple typos.

I'm against parents disciplining teachers regardless of what they do with their own children.

i think parents disciplining teachers' hildren is only fair turnabout, myself.

I have frequently felt a very strong desire to discipline teachers. Strangely, this desire coincides with seeing "their" spelled "there".

Now and than. Here and their.

I think both parents and teachers should discipline children.
