Disagreeing

Absolutely not.

Are you kidding?

Aren't you ignoring the fact that...

Aren't you jumping to conclusions?

Aren't you mixing apples and oranges?

Aren't you stretching it just a bit?

Be that as it may, it still doesn't change anything.

But in the long run...

Even so...

How's that possible?

I can see what you're saying, but...

I can't accept that.

I don't see it that way.

I have a problem with that.

I think you're missing the point.

I'd be interested to hear where you got that.

I'd say you're on shaky ground there.

I'm not convinced.

Isn't that a bit farfetched?

Maybe, but have you considered...

Maybe, but haven't you considered...

Nevertheless...

No way.

No, I'm afraid not.

Not from where I'm sitting.

Not in my book.

Not on your life.

Not quite.

On the contrary,...

Possibly, but I doubt it.

Really.

Really?

That just wouldn't work.

That makes no sense whatsoever.

That may be true, but...

That's a blatant lie.

That's an erroneous assumption.

That's highly unlikely.

That's just not possible.

That's not what I'm saying.

That's not where I'm going with it.

That's only one way of looking at it.

That's out of the question.

There are a few holes in that argument.

There's not a word of truth in that.

Well, that's a new one to me.

What's that supposed to mean?

Where'd ya get that idea?

With all due respect...

Would you care to cite your sources?

Yeah, but then what?

Yes, but aren't you forgetting...

You might want to recheck your facts.

You must be kidding.

You seem to be barking up the wrong tree.

You're missing the point.

You're way off base.

You've taken it out of context.
