Bingo.
This is the exactly why the ACLU has become active in gun rights lawsuits. Although I'm sure that the whole 2nd Amendment concept is anathema to most of their members, it is a right that needs protection from people who consider their own path to be the only correct one for society.
There is no freedom of speech protections EXCEPT as against the government. This has been pointed out in this thread already, but to have a drum beat about freedom of speech on a PRIVATE site that SPECIFICALLY censors / disallows even NON COMMERCIAL speech from US (its membership) in these vary forums seems laughable.
If someone around here doesn't follow the PRIVATE rules of the site, they are banned. Why shouldn't the NBA have the same right of SELECTIVE association that ICMAG enjoys?
