Imagine how cool it would be to see some person yelling about Lenin and Marx, waving their arms around like crazy, newspaper in hand. Wearing one of those old caps, like the one Lenin had.
I know we kind of have a version of it online, but it's much more atomising and lame. Yelling on internet forums will never compare.
The only people who do soapboxing these days are ultra religious nutters, screaming about the apocalypse or whatever. How the great have fallen, truly.
Where is there enough for traffic for people to listen in America? Outside of NYC it's just shopping districts which are usually private property or heavily policed enough to get you thrown out either way.
In my experience it's always the same religious group hogging one particular stoplight to yell at all the people stuck in traffic. Maybe we could get up early, take their spot, and start yelling about the labor theory of value.
