That’s not what you said. you said “if a shitta is something is assur, even if there is another shitta that holds it isn’t assur, a person would not be wrong to state that it is assur.”
A “shitta” means (at least) one person. You say we are discussing where there is only one meikil man diamar… I don’t know where you got that from. It seems, at least from that post, like you are saying we the daas yachid we are sometimes machmir for is the halacha. Which isn’t true.
