There's your problem right there, Ace.
There's your problem right there, Ace.
You got it.
Goverment, with all its moralistic "discrimination" laws and regulations, probably makes enforcing any kind of dress code at a public transportation hub so risky that all they can really do is throw up their hands. They'd constantly be fending off race or sexual orientation discrimination charges. Government punishes harshly for discrimination. Maybe the airlines would like to be more moral and make it impossible for a guy like this to inflict himself on their paying public, but the government gets in the way.
Just one small illustration of how less government would lead to a more moral society.
