Disagree robot: Hi, I am the disagree robot, I will disagree with anything you will say, but I will also give you a detailed reasoning why I disagreed with you.
You: The grass is green.
Disagree robot: The grass is not green but actually brown, the reason being that during the process of photosynthesis the chlorophyll absorbs light in the blue and red parts of the wavelength spectrum and then reflects the green spectrum which is visible to us.
You: The sky is blue
Disagree robot: No, the sky is not blue but it seems blue to us. Blue sky is caused by the Raleigh scattering (Rayleigh scattering) of the sun's light due to the presence of the oxygen in the atmosphere.
You: Two plus two equals five
Disagree robot: No 2 + 2 does not equal 5. It equals 4 according to the mathematics principles. This equation is used from the ancient times, it was first used, to be precise about year 5000 BC, in Mesopotamia.
You: Two plus two equals four
Disagree robot: I agree with your statement, 2 plus 2 is 4, good job.(I am not good at this, please let me disagree with you. I also have to disagree with my statement for it to be valid)
You: You are a robot.
Disagree robot: No I cannot agree with that statement, I am made up of 35% steel, 15% aluminum, 25% glass, 15% silicon, 5% plastic and 10% wood and I am controlled by 245 lines of python code and that is why I disagree with your statement

You: The sun sets on the west.
Disagree robot: No the sun does not set on the west, it actually depends from your point of view, so I as a robot disagree with your statement to be exact, but not in a wrong way.
You: A spider has eight legs.
Disagree robot: No it doesn't have just eight legs, most of them have 8 legs but there are also some types of spiders with 6 legs or even 7, this is caused by some birth defects but they still count as spiders.
