No: Its not radical Muslim extremists beheading people. Its not born-again Christians refusing to bake gay wedding cakes. This time its Ultra-Orthodox Jews refusing to sit next to women on airplanes. (Independent UK link for non NY Times subscribers) It seems to me this is part of a growing trend. And one I think we all need to put a stop to. IMHO religious liberty means being able to worship in the way you see fit in your private life. Go to church/temple/mosque on your own time, on your own schedule. But once you venture out into the wider world - you need to play by the rules the rest of us follow. If your Ultra-Orthodox faith literally means you can't sit next to women, you need to make your own arrangements (take a boat, charter a private flight) - or stay home. As a side note, I think it makes illuminating reading to take a look at a little handbook put out by Pennsylvania's Amish community for operating horse-drawn buggies on public roads: I think a lot of these religious fanatics (or all the major denominations) could learn something from that sentiment.
