You see, this is exactly the reason you are being accused of histrionics. No one on this forum can deny you your First Amendment rights. Someone disagreeing with you and providing facts that you can't refute is not tantamount to denying you a right.
There have been no facts presented by you or anyone else which refutes my position that there are no facts regarding how the confrontation started or who is responsible. The ONLY facts in evidence is that a confrontation occurred and a 17 year old is dead. The only witness, the man who shot the 17 year old has claimed self-defense, and, thus far, the local law enforcment has accepted his word, in my opinion without doing a thorough investigation. The fact that there are so many on this thread who have done their damnest to shut down anyone who is asking for more answers speaks for itself.
