To say it differently, the state of being "asymptomatic" is no different for an unvaccinated person say +16 hours after contracting the virus versus a vaccinated person being "asymptomatic" +96 hours after contracting the virus. Both people are not hacking or feverish or visibly ill (the unvaccinated person will eventually get there at say +96 hours while the vaccinated person may never become symptomatic), but if they have virus particles on their person, .... they are still spreaders.
Like I said, I am very curious about the data that suggests this, and I'd like to understand how the explain/rationalize it.
i think this is where you're making an unwarranted assumption, and the difference is, i think, due to viral load. basically, everyone is not carrying or shedding equal amounts of virus.
i believe, and i do not have a source at my fingertips for this right now, that the amount of viral load a person carries makes the difference in whether they get sick and how sick they get, so while some people may technically have a few particles of virus in their system, it is not enough that they could reasonably infect another person. that is just me theorizing based on what i've learned about how viruses spread in general.
there is data out there about whether vaccinated people test positive for covid and they have shown that vaccinated people are less likely to be asymptomatic carriers as well. again, apologies for not having it at my fingertips... my folder of covid bookmarks has gotten a bit unwieldy in the last few weeks.
Role of vaccines among other preventive measures
As there is not yet any evidence of an effect of the vaccine on transmission, non-pharmaceutical interventions must continue,
including use of face masks, physical distancing, handwashing and other measures based on the epidemiology of SARS-CoV-2 in
particular settings. Government advice on non-pharmaceutical interventions should continue to be followed by vaccinated
individuals, as well as those who have not yet been vaccinated. This advice will be updated as information on the impact of
vaccination on virus transmission and indirect protection in the community is assessed.
For instance, according to Vox, a working paper—not yet peer-reviewed—released Friday in The Lancet assessed thousands of Covid-19 screenings among health care workers at a hospital in Cambridge, England, including both unvaccinated staff and staff who had received the Pfizer/BioNTech vaccine.
The researchers found that, among the unvaccinated staff, 0.80% tested positive for the coronavirus. In comparison, among staff who had received the vaccine, only 0.37% tested positive less than 12 days after their vaccination, and just 0.20% tested positive more than 12 days after vaccination.
According to Mike Weekes, an infectious disease specialist at Cambridge University and co-leader of the study, the results suggest the risk of developing asymptomatic Covid-19 is four times less among health care workers who have been vaccinated for at least 12 days.
Meanwhile, a press released on a pre-published, not-yet-peer-reviewed paper from the Israeli Health Ministry and Pfizer found that the vaccine appeared to reduce all coronavirus infections—including asymptomatic infections—by 89.4% and symptomatic infections by 93.7%.
During the trial of Moderna's vaccine, produced in Boston, researchers swabbed all participants to see if they had any viral RNA. They saw a two-thirds drop in the number of asymptomatic infections among people who received the first shot of the two-dose vaccine, compared with those who received a placebo
The UK trial of the vaccine produced by the University of Oxford and AstraZeneca swabbed participants every week, and estimated a 49.3% reduction in asymptomatic infections among a subset of vaccinated participants compared with the unvaccinated group.

Do Covid-19 vaccines stop coronavirus transmission? Here's what research says.

Can COVID vaccines stop transmission? Scientists race to find answers
hopefully these can get you started
Controlling the pandemic will require shots that prevent viral spread, but that feature is difficult to measure.
But whether these observed reductions in viral load are sufficient to make someone less infectious in real life is not yet clear, say researchers.

As mentioned, "pre published, not-yet-peer-reviewed" studies are not going to convince me. When this is peer reviewed and positively confirmed by multiple independent teams (especially research bodies NOT linked/funded by the vaccine manufacturers themselves), that will become more convincing to me.

then i suppose you will have to wait a bit longer
