How can individual attitudes and lack of response to injustice harm society as a whole?

Not sure if it’s within 12 months, but you could talk about the spreading of alt-right hate speech and whether that is covered by the right of freedom of speech? or, cover how during the midterm elections in some states many native american populations were declined to vote because they didn’t have the proper id, despite being citizens? also, the death of that journalist last month, who spoke freely and reported about the saudi government and how corrupted it is and was killed because of that (lack of free press/speech). just some ideas for this prompt, i hope at least one of them : )

Britain altered native american societies culturally because some of the indian tribes were friends with the british and thought them their culture and the british did the same.some of the tribes didn't like the british and fought against them with france, some tribes didn't want anything to do with the europeans and left them alone.trade with the british changed them economically because they were now trading food for things like guns and blankets.
