think commenting on media cites (newspapers, tv sites etc) has any effect, why not just blow your brains out? I must believe that making the effort is worth the effort.
I believe in the dictum: "Never say 'die'." If you think it's 'over', then it will be.
NOw, regarding this individual with his 'facts' you referred to, I obviously don't know any of the details but I certainly would like to hear this individuals argument and 'facts' to 'have a go' at it. It is a typical conservative tactic to refer to 'studies' by certain groups (like CATO institute of disinformation) and contend that their conclusions are legitimate. It is possible to examine the basis of their conclusions and show they are not legitimate.
I do not think the situation you sited is comparable to responding to a media site. Note, when responding to a media site, they are (excluding Faux News Network*) to a degree, affected by viewer comments. But if nobody who actually thinks ever submits comments - well then, comments NOT SUBMITTED will NOT have any affect on them. When you are communicating with a media site you are going to be read by many people. I do not like to waste my time talking personally to idiots because I am taking my time to talk to one person. If you comment on a media site you are talking to a large number of people at one time (some employed by the media site, and those who read the comments on the site). Thus the time taken is getting you more impact.
I certainly know, however, that if we do not register our objections to disinformation or slanted presentations on media sites your opinion privately held will have no affect.
* However, even Fox News may not be entirely inured to adverse public reaction
