why are our rights such as freedom of speech not unlimited?
ARE they unlimited??
Some are
Then ALL are not unlimited, right?
I believe so...but the are not unlimited so that citizens do not use it irresponsibly right?
That's correct, yes.
Criticism of the government and advocacy of unpopular ideas that people may find distasteful or against public policy are almost always permitted. There are exceptions to these general protections, including the Miller test for obscenity, child ography laws, speech that incites imminent lawless action, and regulation of commercial speech such as advertising. Within these limited areas, other limitations on free speech balance rights to free speech and other rights, such as rights for authors and inventors over their works and discoveries (copyright and patent), protection from imminent or potential violence against particular persons (restrictions on fighting words), or the use of untruths to harm others (slander). Distinctions are often made between speech and other acts which may have symbolic significance.
