Regarding the current Muslim migrant situation, we must use common sense.
Here in the USA, if you have a three bedroom home and if Catholic Charities (the agency which is accepting the majority of these migrants into the USA), were to ask you to take into your home four unmarried able bodied Muslim men (ages 17 to 25) -- two of whom would sleep in your one spare bedroom and the other two would sleep in your living room on your queen bed sofa, would you accept them if you had two teenage virgin daughters (12 and 14) in your other bedroom and you and your wife slept in the Master Bedroom?
Would not this be pure folly?
Even the Orthodox Church requires that male and female monastics sleep in separate monasteries.
