How do I respond to papers that present the authors' views and opinions as scientific fact?
If you believe there are significant problems with an existing manuscript, then you should present these issues to the journal in which the "offending" articles appear. The format this response should take depends upon the nature of the problem.


If the issue is in fact "forging experimental results," then the paper deserves to be retracted. However, this is a difficult allegation to prove, and you would need to have strong justification (not evidence, per se) backing up your allegations. 
However, if the issue is misinterpretations of results or previous literature, this does not quite rise to the level of "academic dishonesty" as forging results. It is not necessarily correct to have the paper retracted. Instead, you should consider writing a "comment" or "letter to the editor" or even a longer paper in response to the problems in the earlier work. 


Note, however, that if the paper has appeared in a reputable journal, it has gone through some sort of peer review process. As a consequence of this, it will be necessary to present a more "airtight" argument than if the paper merely appears in a repository such as arXiv. In the latter case, however, then there's probably not much you can do beyond the aforementioned "response article," as the paper has not been published, and thus retraction depends on the author "self-retracting" the work.
