Local very much matters, for local issues. See the protests directly in Ferguson for example.

The related protests outside Ferguson accomplished fuck all.
If the issue is an international issue, a local protest means and accomplishes NOTHING other than a mild inconvenience for people completely unrelated to the problem.
You don’t think the nationwide protests and international reaction to the killing of Michael brown had any effect.
Would you say there was any effect when politicians and police in areas outside furgeson had to make statements in response to the protests in their regions?
Do you think catapulting blm to the national level and international recognition had any effect?
Since you said a local protest means nothing if the issue is international do you think that the various anti war protests throughout Americas 20th and 21st centuries have meant anything?
Nope, not really:
“Both BLM activists voted into Congress have been pushed out.”
Do you think that those politicians had any effect while in office?
