I can see you're doing a Socratic thing here, but I can spare you the next ten pages of dissembling responses. This is the same argument wareyin uses for every criticism of Democrats: you are allowed to have gripes, grievances and complaints about anything associated with the Democratic Party, provided that you never* voice them to others. You are allowed one (1) disappointed tsk per electoral period, to use at your discretion. Saying anything more is providing aid and comfort to the Enemies of Democracy, who rely on your keen internet insights to point out the flaws in the otherwise famously cooperative closed ranks of the Democrats.
*Exceptions can be made if your complaints are not about the centrists or moderate Democrats who fall under the big tent of the party and must be welcomed even as they torpedo Democrat-led legislation, but rather the accelerationists, purity testers and progressive Democrats who dishonestly argue with bad faith to hamstring the Dems by being super mean about them online.
I don't know how long it's been going for, but iirc I noticed the pattern back in 2020 when it was vitally important that no one point out Biden was already old as ◊◊◊◊ and shouldn't be relied on to be capable of running for reelection. Boy was that egg on my face!
