But we don’t even need the sources to show how wrong this is. For example, even you admit that “There are certainly many mixed events. However, none of those are obligatory and nothing is mandated.”
It’s scary that you can’t even see how wrong this is, and that you write this as if it’s some sort of defense of MO.
As you surely know, if a person has a choice of two streets, and he knows that one of those has pritzus and he chooses to go that way EVEN IF he goes with the full intention of not looking AND DOES NOT LOOK then he is called a RASHA!
Yet you have no problem with a putatively “Orthodox” institution ignoring all of this and institutionalizing “many mixed events”?
