How to crush sicilian defense and ruin black's hopes and dreams

The Sicilian is sound, you cannot crush, ruin, or punish it.
Sharpest is the open Sicilian: 1 e4 c5 2 Nf3 d6/Nc6/e6 3 d4 cxd4 4 Nxd4. White enjoys a lead in development, but black has an extra central pawn.
Solid are 2 c3, 2 Nc3, 2 f4.
Good are also 1 e4 c5 2 Nf3 d6 3 Bb5+, 2...Nc6 3 Bb5, 2...e6 3 d3


You can't crush it, but you can play better against it. It takes a fair bit of situational understanding to play Sicilian well for Black. So keep pressuring them and attack the kingside. Hold the centre and you should be fine. Just develop your pieces, castle. Pay attention to threats on the board as they emerge and as white go for the kingside. Black will be attacking the queenside usually.

I already did that lessons course. It looks like a fun way to play for 1. e4 attacking players facing the Sicilian and wanting an interesting game, but I'm a 1. d4 player who tends like like more positional chess and I partly watched the course for entertainment and expanding my overall knowledge.

1. e4 c5 is not a "sussy" move by black. The Sicilian Defense is a popular mainline opening and all mainline openings tend to be pretty solid as they have usually stood the test of time. If you want to beat mainline openings, then it usually involves just studying theory and choosing a strong mainline response.
Playing sidelines and gambits (although sometimes solid) are mostly just hoping for your opponent to not know the position as well as you, but as you get higher and higher rated, opponents will tend to know more things and mainlines become slowly more and more necessary.

In the book the ideas behind Chess Openings, Ruben Fine discusses this idea of the e4 pawn not being supported on move one as opposed to the d4 pawn being supported by the Queen. when I made the connection that all e4 defenses involve an attack on whites e4 pawn either directly or indirectly it really made an impact on my understanding of the game.

1.e4 c5 is craven. End black's Iron Dream by calling forth Agent Smith-Morra from the Chess Matrix and force black to prove he's not a kitten masquerading as a lion.
Regarding #14, the Wing Gambit, what Yerachmeal is showing definitely isn't how to play against it. Black went wrong on move 3.
I showed more than one response to it from black.

you cant refute the sicilian but if you want something that is easy to play and is aggressive i would reccomend taking a look into the grand prix attack, or the smith-morra gambit

well chess is hard, theres not an "easy choice". but both smith-morra and grand prix attack have thematic ideas and are very aggressive so i think thy are good choices when dealing with the sicilian.
This will throw people off and is still good even if black knows how to play it.
Better
I think you and I have watched the same shows...

smith morra gambit! at least SOME sicilians hate it. I have winning stats with it, and haven't studied it in a decade. some GM stated that it puts A LOT of pressure on black and that it's much easier for white to punish any mistakes black makes than vice versus, forcing black to play defensively
stats are 1600-2000, and 52:45 is my own exact stat too after 4.Nxc3. that's without doing my homework. it's a complicated transpositional maze if you want to play the strongest lines and study the theory. it got sooo unwieldy, I gave up on trying to create a book for it after I was unable to navigate the transpositions at something like 30 plus in a wall of 200 plus lines
