It is definitely more inherently difficult to build than to destroy, i.e. to move forward rather than back.

Moreover, most of the time when conservatives seem to argue on the internet, truth is not even a minority portion of their goals. Thus, liberals aim to argue in order to become correct - bantering back and forth the details until the most proper course of action can be decided upon that takes into account all of the facts - whereas conservatives argue in order to be effective, at "winning" the goals already given to them by an authority figure, who they presume to know more than they personally about all subjects (maybe God Himself even, via their chosen shepherd here in Earth, in spite of literally everything God has ever said in the Bible previously, such as the workers deserving their wages, taking care of widows and orphans, and other social justice matters).

So yeah, arguing "facts" with someone who has already decided their position in advance and is not listening to new ones coming in, is indeed a huge waste of time, most often. Sadly, I don't know what would not be a waste of time, in terms of convincing conservatives about any factual matter. In the analogy above, until those coal miners saw for themselves that they were being evicted from their homes and could not purchase groceries with all the non-existent money that was promised to be flooding in as "clean coal" was to make its great comeback, I am not certain that they could be convinced by any means? In fact, I bet many were not convinced even after they became homeless - surely it was just their bad luck that they could not wait for the clean coal revolution, or you know what, I bet it was those damned dirty Democrats who did it, somehow!? (despite not being in charge of pretty much anything for multiple years straight) "Lock her up!", no matter what she may or may not have done, bc it's a convenient scapegoat.

And it's not even that they are brainless, it's more that they do not choose to engage their brains in these matters, preferring instead to defer to authority, whenever their brain comes to a different conclusion. So what is that precisely... laziness, perhaps? Or just flat gullibility. In any case, most definitely an easy target to aim to exploit, by oh let's say some nation that would like very much to switch the USA from a foe to a friend to its goals, or at least neutralize it.

The founders warned us about all of this btw, saying that it would lead directly to the death of the at-the-time still fledgling democracy. We chose not to listen, and we've been coasting along ever since, likely protected more by the large oceans than anything else, back when that was a more daunting technological hurdle to have to cross.
