I read a thesis right here on FR about those stupid beards:
Young men nowadays have absolutely no idea what it is to be a man. No one ever taught them. Their parent failed them utterly, and society no longer presents manly men in a positive light. All heroes nowadays are anitheroes, fighting racism, or something.
However, they ache to be respected and be considered men, and yet it is beyond their ability to be actual men .
Thus, they follow trendy fads, just like a chick would, and one fad is the stupid beard. It is a signal to others: “Look! I’m a man!”.
But they manage to somehow seem even more metro and effeminate with the stupid beards, so it’s backfiring.
