This Mezuza vort is. like so much else, something that sounds good in a speech but doesn’t really hold water.
That’s not what a compromise is.
We are careful to fulfill both shitos with Mezuza, like in so many other areas of Halacha.
Of course compromise is good, in מילי דעלמא. Like all Midos, “easygoing” has applications both לצד הטוב and לצד הרע. It is not good to compromise on מילי דשמיא.
Compromise for compromise’s sake is not laudable. Compromise for the purpose of being מרבה שלום is good, as long as the שלום in question is רצון השם.
