You are right about "the loudest voices usually get the most attention", but not always the smartest ones... But, it is also true that times are changing, and with censorship, we don't even hear any voices that are "different"... We just hear a certain level of "opposition"... And that's the biggest problem...
We have given too much power to those with "loudest voices" and we can't hear anything other than them... As I said in my reply to @achim03 comment, this is the moment where decentralized social media networks are coming to "save the day", with the problem of "waiting that day"... lol...
As there are still too many people living in a dream that people with a laudest voice will listen to them and change something... The problem is that you and me maybe need a change, but the guy with a loudest voice doesn't...
Cheers!
The loudest voice is driven by Fear and Ego, It is driven by insecurity and a desire to control.
The voice that is most effective is the considered, informed and knowledge driven. by sharing information a swarm effect takes hold and eventually there is no choice but to follow the direction of the swarm
