When Michael Moore had to cut off Hogg's microphone because he was saying stupid shit should have been a big clue that Hogg should never be given any power whatsoever. He should not hold a party office. He clearly should never hold public office.
He is useful as a street level rabble rouser, but nothing more.
Taking a minute or two to parse your post:
On September 10, 2018, roughly 7 months after the Parkland High School Massacre, Michael Moore invited 18 years old David Hogg to speak at an event. David Hogg encouraged Canadians at the event to make financial contributions to American political candidates. Michael Moore informed David Hogg Canadians cannot legally contribute financially to American political candidates. No enmity between Moore and Hogg.
Since that incident, David Hogg, who turned 25 on April 12th, has completed a degree at Harvard, continued his political activism and won a seat on the DNC as a Vice Chair.
The DNC, with Jaime Harrison as Chair, failed the DEMs BIGLY! I donated $100 to the Jaime Harrison Campaign when he ran for the U.S. Senate against Lindsey Graham. Harrison lost

BIGLY.
In 2020, the DNC, with Tom Perez as Chair, defeated Chump! Woo Hoo
Do you remember thinking Florida Congressional District 13 DEM Candidate Witney Fox stood a chance of upending Anna Paulina Luna? I live in that district. I met Rep. Luna in a cordial situation at a fundraiser. I voted for Fox. I didn’t think

Fox stood a remote chance of winning. I guessed right.
GOP incumbent U.S. Rep. Anna Paulina Luna, who defeated Democrat Whitney Fox, said her first priority for her next term would be securing the southern U.S. border.

I didn’t expect Chump to win the 2024 Popular Vote; in fact, I bet $11,000 Harris would win the Popular Vote. Very disappointing result!
I didn’t expect Chump to sweep the 7 Swing States; I bet $6000 he wouldn’t sweep. Again, very disappointing result!
I made and lost two more parley-style bets on that General Election. In total, I I lost $25,000 overnight. Shrug. Fortunately, it hardly made a dent in my lifestyle.
I know this: I drank the kool-aid. Until you and i can find our way to the same page, the DEM future continues to look very DIM!
Hats off to David Hogg for rabble-rousing!
