Congress shall make no law ..... abridging the freedom of speech .... This part of the first amendment is not a "pass" to say, write, or post anything you want. Not all speech is protected - never was and likely never will be.
1) Be factual and tell the truth: Knowingly false statements that rise to the level of defamation (slander/libel) are not protected. For example you are not protected if you distort facts or lie in a way that damages another.
2) Can't yell fire in a theater or bomb in an airport: Speech that incites is not protected. Threats, in general, are not protected.
3) Obscenity, what would that be in 2016?? I am scarred for life by things I have seen on PitRacer. Some damn evil Vet Forum posters know when and what I am talking about!!!
4) Stealing speech owned by others, not protected.
5) Commercial speech: False advertising for example is not protected.
Most everything I read on PitRacer is pretty constructive and dang amusing. Sometimes things get stupid and a little out of control but that is the exception.
Or just maybe I give us all too much credit. Has anyone with a Pitracer ID that ends in 250 been contacted by a JS7 lawyer???? Come on - we just gotta know!!!! LOL.
