helpful pointed out that there is a preference for married people in some inyanim. you can apply it or not apply it where you choose.
And I pointed out that there is a preference* for kohanim in some inyanim. What if I choose to apply it to posting in the Coffeeroom?
In other words, just because one type is preferred in one situation does not make it valid to apply that same preference in any situation — at least not without stating the commonality between the two cases that makes them comparable.

* Granted, the example I chose above is not a preference but a requirement — but there are enough other areas where we give deference to kohanim that one can easily make the same argument.
