ggp isn't being dismissive or incurious. They say they are skeptical of the reasoning used in the science.org article, but are still open to the accepting the conclusion. Does being curious mean you aren't allowed to question anything? gp is probably being downvoted for dismissing ggp's concerns with a trite "please educate yourself" and not actually referencing anything to read. Telling someone else they are wrong and to go find evidence to support your own opposing view may technically be "encouraging curiosity" but it's certainly not curious itself.
