It's just that a lot of people argue badly, either because of lacking skill or lacking goodwill.

That doesn't mean their arguments are necessarily wrong. It is necessary to try to reframe such badly made arguments in a way that presents the message properly in order to be able to actually compare competing ideas and find truth.

If you compare one well-crafted argument to a poorly crafted argument, the well-crafted argument would seem to come out on top even if its underlying ideas were actually wrong.

E.g. if I say "Apples are good because my grandma loved apples and you are stupid!"

And my opponent says "Apples are bad because there are other fruits that can be grown much more efficiently and feed people better"

Then my opponent would probably "win" the argument. But that doesn't mean apples are actually bad. Try to remake the argument for why apples are good in a better way, in order to fairly compare the two sides and find the truth.
