agree with vs agree on (I agree with/on whatever you have said.)

[Daemon99]

I know that I agree with you on that is a well-formed sentence. But I want to know if the following sentences are correct too.

1) I agree with whatever you have said.
2) I agree on whatever you have said.
3) I agree on that.
4) I agree with that.

Daemon99, they all seem OK to me, although 1 & 4 seem to fit the context better.

With being the stronger connection to the speaker.

Hi Daemon,

'Agree on' is usually followed by something like 'plan' 'scheme' 'strategy' and words like that rather than on 'that' 'whatever' and so on.
