Agree with or Agree to

[José Manuel Rosón Bravo]

Good afternoo (in Spain):

I have a question for you:

How would you say ?

...agree with my proposal.

or

...agree to my proposal.

I have found these two possibilities on the Internet almost in the same frequency. Obviously, it is not the same result for it is not the same expression.

To be a purist, which one would be the correct way?

Thank you very much

According to 'Practical English Usage' by Michael Swan, you could get what you need.

a.agree with a person, opinion or policy
I entirely agree with you.
He left the firm because he didn't agree with their sales policy.

b. agree about a subject of discussion
We agree about most things.

c. agree on a matter for decision
Let's try to agree on a date.

d. agree to a suggestion
I'll agree to your suggestion if you lower the price.

I'm not quite sure whether both are correct, though. I think both possible.

On the victory side,
