I think of my experience with real world technical people, maybe 2-4% are denialists but those are also very vocal (enough to saturate a place like this). Another 4-10% are under the sway, and I think that's a fairly reasonable assumption since in Sweden the party that represent those that would vote for the current US admin manages to get about 20% of the electorate (although possibly more in the younger age groups).

It's also a reminder that this is a well known public forum at this point, and those are always targeted by propaganda (or have gotten a large enough mass that denialists have gotten a large enough foothold).

Back in 97-00 slashdot was an amazing site, just a gathering of inquisitive people posting cool stuff. Over the years it degenerated with more hateful stuff despite valiant efforts to adjust moderation causing early people to drop off, this place was amazing back in 2015 when I joined and the work done to keep it somewhat tidy after some 18 years is actually impressive, but I'm also feeling a lot of the same types of comments increase that made slashdot a less interesting place to begin with.
