Same reason, along with seeing kids with runny noses running all over the place, that I stopped going to Target and places like it.
The "elitists" and their families will never be subjected to situations like this, and they don't care a bit that we are forced to.
I'm sure my action on that bus would be called "racist" or "xenophobic"
by Ivy League professors that have never ridden a bus...
but I suppose I was a little sensitive to the problem as I'd recently seen
a documentary of two US doctors that had been forced to cobble together a
cocktail of donated US pharmaceuticals in order to treat resistant cases
of TB in South America.
I felt sorry for the rider. But if there's one place in the USA where an
illegal can get medical treatment (even better than any I could afford)...
it's Los Angeles.
