Honestly, this comment of yours is probably more a reflection of your own values than of reality.

It is possible that right-wing sources, or particular types of right-wing sources, have a greater tendency to create disinformation or fabricate facts than left-wing sources. However, the opposite could also be true in some cases; left-wing sources may sometimes be more likely to label their opposition’s claims as misinformation rather than recognizing them as competing interpretations or arguments.

For example, some sources labeled certain claims about natural immunity after exposure to the virus, including claims that it could provide stronger protection than boosters in some circumstances, as misinformation. However, certainty in any broad generalization, such as the idea that natural immunity is always better, hybrid immunity is always better, or mRNA vaccines are always better, would be inaccurate. The reality is that the effectiveness of different forms of immunity depends on many factors, & people continue to study how these factors interact. Outcomes can vary depending on individual circumstances, such as age, comorbidities, immune status, prior exposure, and other whatnot.
