The effective kind of activism

Activism is huge when it comes to creating a change. There is all sorts of activism that we see being taken around the world since the beginning of time. We saw Ghandi go on a hunger strike, or Martin Luther King Jr. marching to the nations capital. Although there are many different kinds of activism it sometimes is hard to decipher what is the right kind of activism.
When we watched in class the protesters in Mizzou there was one kind of activism. We saw these students create a blockade so that the president was unable to pass them and therefore had to listen to what they had to say during the homecoming parade. This was a more physical activism that was held. This activism may be seen as effective to some because people were forced to listen to them and they were not moving. However, some other people like some of the parade goers may have thought this was not the way to go about it. We saw some Mizzou fans trying to get them to move out of the way so the president could go on with the parade. These fans may have seen this type of activism as disruption to their homecoming parade and didn't think it was effective.
At our school we saw a different kind of activism. To coincide with the African American students at Mizzou three African American students at Alabama shared their personal stories with how racism has effected them here. Although this is not a physical sense of activism it still was very effective because it went viral and many people were able to hear the personal in-justifications they have faced while being at Alabama.
In another video we watched it showed how undocumented immigrants went about showing their activism. After one girl's mother got taken from her and was to be sent out of the country she started having people sign a petition for her mother. This petitioning ultimately worked in her case and she was able to have the bus that her mother was on turn around and she was able to be with her mother again.
Although there are many kinds of activism it is hard to distinguish which the most effective kind of activism. Is it something physical so people are forced to hear and participate with? Or is it something that is an option that people can listen to so they can hear about personal stories of those who have felt some kind of oppression. Or is it something where having power in numbers and getting people to sign a petition?
