This is what always gets me. People claim to love science but don't listen to it or have a basic understanding of the actual process. We can see it with hot topic issues like the current covid crisis or global warming. People take the easy positions and say because of that that they understand the science. But in reality science is extremely nuanced[0]. It isn't so much the lack of nuance that makes these people harmful, it is that they are adamant that they are well researched.

We make the jokes with anti vax people that just because a baby came out of you doesn't mean a PhD did. Yet, I don't think how many people realize how harmful it is to oversimplify these topics. We can't solve these big complex problems if we make them politicized and just pretend that there is a singular and simple solution to everything. And that everyone that deviates slightly from the accepted dogma is a heretic[1] (which ironically tends to include a significant number of scientists in the field of concern).

[0] As an example, there are many, even here, that think we just need solar and wind and we'll solve global warming.

[1] I say that these are armchair scientists armed with a baseball bat.
