Maybe those men who wish this 'trend' to die, cant grow a beard themselves and its a jealous thing?, its not just the beard itself, if you haven't noticed, those with beards keep their chest hair too.
Remember men waxing? That was a 'trend' too, it was not normal for men to wax, the only reason some men waxed their chest hair was a body builder thing and competition, add oil on skin to a muscular physique and it stands out.
So, for gay men, waxing and shaving is out and natural, trimmed, sculpted hair is in, straight men have always been behind trends and are still in the waxing and clean shaven era, straight men are really into shaving all their pubic hair...ewwww
I don't see the gay guy beard trend dying any time soon, as long as apps like Scruff are around, I think its wishful thinking on some mens part, soon, straight men will catch on
