Don't Strawman and generalize - provide an argument relative to this context, if not then the merit of your argument stops by simply changing the content. For example if we were to insert Hitler now your generalized argument looks ridiculous because of course the problem is that people agreed with Hitler.

When a person's opinion is based on literal fabrication of information, based on soley on belief, and is irreconcilable with the truth, yes, the problem is absolutely with them and parties involved.
