And at this point, as a Catholic, I’m wondering if it’s morally allowed to fly in the United States.
If your need to fly requires that people with prosthetics and colestomy bags have to be abused, then you don't really need to fly.
There are OTHER WAYS to handle this. CAIR won't like them, but they're complicit in the terrorist attacks anyway ~ their opinions can be safely ignored ~ Woodrow Wilson would have imprisoned them.
