“Would you describe R’ Herschel Shachter as Modern Orthodox? ” Yes, I would. He, BTW is a member of the RZA. He, along with R’ Willig would be considered (if the MO had ones like the Yeshivish) the MO Pope. Here is where you are getting things wrong, you see a Rav, who is respected and doesn’t “compromise” (whatever that means) and by default that means he must not be MO. Your mention of kiddush with single boys and girls is funny, because I don’t remember who said it, but one of the YU Roshei Yeshiva said that all weddings, even separate, should have a mixed table for the singles to meet.
It is one thing to discuss and debate, but when you state
“when we say “Modern Orthodox” we do not mean “Contemporary Orthodox”. Rather, we are referring to a branch of “Orthodoxy” that compromises on Halacha.”
and
“And Modern Orthodoxy compromises on Halacha.”
it just shows what agenda you have and how biased you are against people that don’t follow your thinking. If anything, one can arguable state that it is the yeshivish people who compromise on halacha.
