One uses the word “outdated” solely to push an agenda.
Outdated things can become trendy again.
Got it, so magically ideas can stop being outdated, because some humans said so, but also ideas are outdated because some group of humans at some random point in the past starting calling it that too.
So I am again not sure if you use this word correctly. Is this a case of lost in translation?
No, this is recognizing a useless word, and that most people are too stupid to speak of concepts impartially.
