I have found that the issue is often that people tend to not realize they're arguing that 2+2=6, they think they're arguing what ice cream flavor is the best
This is exactly the sort of argument that I was thinking of when I wrote the comment. We can agree to disagree on the best ice cream flavor, because everyone has different tastes. We cannot agree to disagree on whether the earth is flat, because it's not and we have overwhelming proof that it isn't.
Agree to disagree is for things like "what ice cream flavor is best", not for things like "2+2=4".
I guess we'll just have to agree to disagree on that.
