That looks like a personal anecdote to me, exactly like what the other guy said.
He said "in my country such and such happened". And you're saying "here's an example of such and such happening".
EDIT: But now that we're at it,
> The Wounded Knee Massacre, also known as the Battle of Wounded Knee, was a massacre of nearly three hundred Lakota people by soldiers of the United States Army.
300 people seems like nothing compared to the number of people that dies every year due to (civilian) gun violence. You're just thinking binary, you're not thinking with numbers. Also your best example is from 1890. Roughly the same amount of people that died in school shootings in the first three months of this year. Your commitment to ideology is hilarious.
You asked for a citation, you were provided one. If you think 300 unarmed civilians being murdered by the government because of their race is "nothing" then there is nothing left to discuss. I am honestly worried about what you might think of Mao's China or Hitler's Germany and their respective civilian disarmament; I bet very few lives were lost to "civilian gun violence" under their rule, too.
China never had a citizenry widely armed with firearms.
Germany was also never widely armed prior to Hitler. This is an urban myth.
Only a handful of societies have ever had widespread civilian armament. Certainly not enough to make any kind of causal inference about the general effects of firearms on revolutionary or counter-revolutionary activity.
And Wounded Knee? This was a continuation of a policy of Manifest Destiny and genocide that saw hundreds of massacres and battles. The many armed battles that took place would suggest that being armed wasn't a significant deterrent to US cavalry.
PRC had massive public firearms ownership stemming from people's war, villages were settling beef with home made artillery into the 90s until gov crackdown.
