Um,
I don't see anybody introducing a law to prevent this movie from being shown.
I don't see anyone filing a lawsuit to prevent this movie from being shown, unlike the libs did to Sinclair and to the little movie theaters.
I see a business deciding not to air a program on their station. I see businesses declining to spend advertising money to sponsor a show they don't think their target audience will be watching. I see private citizens telling their local stations that they won't be watching the show.
