I’m not historian but for example I could challenge the idea that a rhetoric about strength and keeping a masculine ideal for the young male population was non existent in European feodality where only nobility had the privilege of fighting, and 90% of the population were farmers. Or that 2000 years ago Jesus already challenged the idea that men needed to be strong in the traditional sense, and that real courage was loving and forgiving among others. I could go on with fashion and clothes but maybe just look at a West European king painting to reevaluate what masculinity is supposed to look like traditionally.
My understanding is that your rhetoric appears only recently (and is therefore not traditional) coinciding with nationalism rise and the need for bodies to throw in the total war (another modern invention) meat grinder.
You can disagree, and I’m open to hearing your counter arguments, because I’m not dismissing you as biased.
