MM:
Now you are just grasping at straws. I live in a community in NYC that is considered one of the more yeshivish places. Not one of my rabbeim, Roshei Yeshiva, or Rabbi’s from any of the shuls would even hesitate to invite people from the community over to their house for a shabbos meal.
He is inviting guests who are as religious as he is to his house and he goes to them because of kiruv???? (sarcasm)!
