They know their supporters. If I show them a chart of a Hockeystick with the hidden decline or a chart describing the difference between observations and models, they ask about experts behind this. They say openly that they can’t read the charts and that they want experts’ opinion because of that.
This is why the claim of ”97% support” is important to them. Because Who is the most important question, ad hominem attacks to the ”deniers” is a relevant tactic.
