Isn't inciting violence the line even in the US? or is it specific call to violence in an organized fashion?
Depends. If you're saying something vague, it should be fine. If you explicitly say you're going to do something violent, that will get you in trouble.
Example : "people should arm themselves, carry concealed weapons, and be ready for anything." - all legal in the US, and this is not expressing criminal intent.
