On the contrary, trolling is a vital art that rejuvenates public life.
This guy's sin is that he is not skilled at his art. A troll who elicits
pity instead of anger is like a comedian who isn't funny. For all this
work, we deserve better.

On to the response:

features and did something revolutionary!

That description fits several of the Scheme implementations we already
have, most especially Racket.

Racket

Racket

most users, just as Turbo Pascal was better than all the competition.

Racket

They want you as a new recruit: https://racket-lang.org/common-plt-app.html

If only PC-SCHEME for MS-DOS still ran. Wait, it does.

The "Fork" button is right there.

Nothing in Scheme is hampered by bureaucracy.

SRFI is entirely free of buraucracy. Not a committee in sight.

RnRS is not hampered by bureaucracy, but by scope.

To everyone else, I recommend

Lisp perspective. And to everyone who can stand millennial culture,
Eminem's "The Fall" as a recent example of how a man responds to trolls.
