I don't hate anyone, any culture or anything. MS, another misconception is that, at some period in 'recorded' history, some believed the Earth to be 'flat'.
History is "my thing".
Aristotle in De Caelo, debated about the earth in space. Thanks to his words, we know that Pythagoreans (the pupils of Pythagoras) claimed as their teacher did before, that our planet revolves into a center of fire. This is completely the opposite to everybody's view in that time where the earth was considered the center of the universe and every planet and star revolving around it.
So, in part 13, where Aristotle talk on theories about earth, while he establishes that the earth must be spherical for such and such reasons, he also mentioned to Anaximenes, Anaximander and Democritus, who said that in order for the earth to hold itself over the air, it must have a flat form. Having a flat form, the earth will compress the underlying air and the earth will hold itself without moving.
The good thing about the philosophy of Aristotle, is that he won't care much about the inclusion of the opposite thoughts given by others. It is understood that he didn't want to impose his thoughts to any one, but on the contrary, he always compared his version with the opinions of others. Of course, his conclusions will be on his favor.
But, thanks to the inclusion of the other's ideas, we know what was the general thinking in those years, and even when Pythagoras never wrote anything, we have that thanks to Aristotle we can acknowledge of his philosophy.
I think, that in each topic, it is good to have both sides, perhaps three or more sides giving opinions about the topic itself.
After all, this is how knowledge increases, and readers have the free will to take one, two, three or more, or none sides about the topic.
It is healthy to mention both sides of every controversial topic, and this is why forums are very popular and how participants can learn a lot.
