You seem to have interpreted this in a strongly partisan way for some reason. Nobody accused any specific party or groups of spreading disinformation. This was not a tribalistic argument. and by your own account you seem to understand that disinformation is something that should be combated with critical thinking, so you seem to acknowledge that it is a problem when people decide to believe in falsehoods. "All sides are doing it" doesn't diminish the problem, if anything is shows how severe the problem is. Critical thinking is a good skill, but it's a hard skill for a person to develop if they are overexposed to disinformation. People cannot be expected to figure out what the truth is if they don't have trusted sources of information. You either have to guess who is telling the truth and hope they are right, or you have to assume nobody is telling you the truth and stop caring.
