The Civil Rights movement can officially declare victory, if this is the kind of racism being faced by African Americans today. Seriously, if the harms are really this trivial, let's move on to other issues. If there is still meaningful racism out there, let's stop clogging the courts and wasting our time with this kind of trivial BS and work the real issues.
Postscript: It could be that I am just not hip to modern lingo. I suppose that the words "please turn off your cell phones during the movie" is actually a well known code phrase meaning "back to slavery all of you" and I am just not aware. If I am missing something, please let me know so I too can feel appropriately victimized next time I go see a movie.
