Answer:
For the first, I would say being poorly represented.
For the second, ignorance and morals.
Explanation:
A lot of people have been raised to demand a change when they see injustices, some might go at it in a violent way, others might approach it in a more peaceful way. One thing you have to know about making big decisions, is that you will never please everyone. Someone is always going to be mad. It depends on their moral values as people. If you saw something that you thought was morally wrong, you would be upset too. They have tried peaceful protests and weren't heard, now they choose to incite violence because they have a voice and are represented in the media that way.
It all leads down to morals. The media says that if you aren't for it, you're automatically against it. If something the media does or activists do doesn't allign with people's morals, they choose the complete opposite because they think that's their only option.
