zahavasdad -“If you dont want to sit with the opposite gender on the bus or Subway, then Drive your own car or hire your own private bus”
How about asking them to move to the back of the bus? Both have paid full fares -if there is a way to accomodate both – why not? If there is a reason for women to sit in the back of the bus -it’s not discrimination. You seem to be college educated -so you should know the difference. Discrimination is doing something based on their race, gender, religion & so on. But you are deliberately ignoring this.
If the Frum Jew and the Non-religious woman can be on the same bus and it’s only a minor inconvenience for the woman passenger (she has to walk a few more steps) -why are they in an uproar? The only reason I can come up with is -“We hate your religion and we won’t even lift a finger to let you practice it!”
