Well if we are going to follow the Rema I look forward to everyone wearing tefillin on Chol HaMoed, eating dairy an hour after eating meat, and going home immediately after maariv on seder night rather than staying in shul to recite Hallel.
I don’t think anyone was advocating a rule that “we always follow the rema.”
I don’t know why you would read these comments in their most extreme form.
Also, the rema says to be machmir and wait 6 hours (YD 89:1). And I do wear tefilin on chol hamoed, and I don’t say hallel seder night in shul. So not quite sure where you’re going with that.
