I hope we all have a sense of humor, even in culturally sensive topics :-)

Yes, I'm concerned as well. I'd like to see an overview of all the
direction-dependent properties/aliases/values that one plans to
propose. For example, will there be aliases for the
top/right/bottom/left properties? 

In general, I do not believe one can simply switch writing direction
and reuse the same style sheet; there are more properties that
should be adjusted when the writing direction is changed. As such, I
believe your :rtl, :lrt, :ttb proposal has the potential for producing
better typography as you can add more declarations. E.g.,

p:rtl {
  font-family: ...;
  margin-right: ...;
}

p:rtl em {
  letter-spacing: ...;
}

What do you have in mind?
