This falls under Social Issue. Those scraggly long beards are real popular nowadays. Lots of Trump supporters seem to have them. I think they’re sometimes called terrorist beards. Anywho, why do so many men wear their beards like that? My guess is there’s some psychology going on. I’m thinking the look is associated with tough macho men like the frontiersmen of the olden days (think Revenant). BUT these men really are small minded sissies inside and so they have these beards to compensate. Kinda like a bully actually feels small so he takes it out by acting tough.
