It seems you are stating that the loudly-spoken and widely-distributed words of the US president are "not important". I completely disagree with that. What the US President says is definitely important. I have already expressed anger in this thread that Biden has not taken the right actions. His words aren't even right. But there IS a difference - it DOES matter what he says.
Denial is not the same as acceptance. Saying that it doesn't matter if the president is a climate denier or not is pretty far out there - I haven't heard this take before.
Is it okay for the president to spread messages of pro-genocide and hatred? That doesn't matter right? The president's words literally don't matter, so whatever, he can go on about yelling that he's gonna nuke someone, doesn't matter. "Words [of leaders] don't matter" is a terrible take.
