I read in the Feb. 15-21, 2003 TV GUIDE that after complaints about Bart's claiming to have Tourette's Syndrome, (Shticks and Stones), the reference in the repeats were changed to "rabies".
Political incorrectness is what makes this show refreshing!
In a time when our own politicians and educators are doing all they can to destroy our first amendment rights, television producers are giving us "reality" shows where the outcome is planned in advance and religious nutcases are demanding that we join their cults or be killed, it's important for the producers of shows like The Simpsons to refuse to pander to pressure groups of any kind!
The producers should NEVER respond to complaints of "inappropriate" material, NEVER change a script under pressure, NEVER allow special interest groups to control the show!
I've never heard any obscenities on the show, and allowing individuals to censor the show to fit their own warped sensibilities, (or their desire to control others' thoughts), further diminishes our freedom.
Don't let it happen!
