How To Do Zimmun

Question
Shalom HaRav,
I hope you and your family are well and enjoyed the haggim.
I have a Question about conducting a zimmun in non-ideal circumstances. With guests yesterday, I tried following the recommendation of the Mishna Berurah that the mevarekh be mossi everyone else for the first berakha alone. I chose this as a compromise, out of concern that guests would be uncomfortable following the original practice of being yossei from the mevarekh for the entire birkat hamazon.
A very pious and knowledgeable guest pointed out afterwards that the practice risks our causing some guests to be mevattel the misswa d’oraitha of birkat hamazon entirely because they do not concentrate and cannot understand Hebrew well. This is especially the case in Givat Shmuel where there is a large range of levels of religiosity and knowledge. The Mishna Berurah only makes the recommendation under the premise that the mesubim will concentrate and understand. What should I do when this might not be the case for some guests?
And how valid is the Mishna Berurah’s apparent assumption that one who does not understand Hebrew is better off reciting birkat hamazon himself? Why are we not concerned about this for other berakhot such as qiddush?
Many thanks in advance.
Kol tuv,
J

Answer
Shalom J:
Good to hear from you.
As I pointed out years ago, in the Shibole HaLeqett it is implied that the reason people began reciting BHM individually is due to problems with the Hebrew. Even if one understands Hebrew fairly well, it is somewhat more difficult to concentrate on what another person is saying in a language which is not your mother tongue. I.e. – the widespread custom of today is a product of Galuth.
B”H this problem is gradually dissipating as more and more Jews are more and more familiar with Hebrew.
I suggest you say to guests as follows: I shall recite it out loud, as stated by Hazal, and all those who wish may be yosse with me as long as they listen and follow every word. If you prefer, you may recite it yourself.
You thus allow each to do what he/she feels most comfortable with.
Shalom
