1. One example of this phenomena can be found in the movement where football players and other athletes would kneel for the national anthem. Many found this offensive so completely disregarded the argument that these people were making. For them it was just a matter of, "you have to stand for the national anthem" as opposed to asking why these people were kneeling and working towards a solution. Their displeasure was their rationale for not engaging with the protestors in this movement.
2. There was an instance in which Obama was heavily criticized for becoming emotional during a speech offering his condolences to the victims of a mass shooting. This was cause for many to dismiss his argument that there should be common sense gun laws and other legislation.
3. The "Starbucks While Black" incident is one instance where I have seen difficult standards prevent people from engaging with an argument. Many have used the excuse that the police where just doing their jobs rather than engaging the fact that instance was a result of racism.
