"Disagree" describes a wide range of things though. It can be "you claim facts that are demonstrably false", "you claim facts that I cannot demonstrate are false, but I have strong doubts and you do not provide sources", "you cite correct facts but your interpretation of them is demonstrably wrong", "you cite correct facts but I interpret them differently", etc. And those are just factual disagreements, without getting into "you're making a strawman argument", etc. Thinks probably shouldn't be this fine-grained, but I hope you get the idea that there is reasonable room for more helpful feedback than "I disagree".
