yes, of course. I also do think that a direct confrontation with anti-science movements is one possibility to reach more people. E.g. when scientific response posts are written and then linked to the the comment sections below anti-science posts.
Such responses never convince the hardcore science denialists, but serve as a counteropinion for those who are still insecure on their position, and in search for the "truth" behind conspiracies.
We could even think about systematically upvoting such comments to make them trending and to appear right on top of all the circle-jerking crap.
