Why does the good sometimes invoke bad?

This week I have been reading up on the “Free Hugs Project”.  In the most basic definition it is “A friendly embrace will put a smile on your face”. This organization, started by Ken Nwadike, a young black man, purpose is to bring peace to hostile situations, by braking the tension with a hug. As we all know in the recent months, there has been many shootings between police officers and black men and women. However from the articles and videos I have seen affiliated with this project, there have been three sides taken. One, which is the “this doesn’t effect me”. But the other two, for and opposing, these have become two very valid and heard arguments.  The for argument is one who just wants peace, who say that the hugs and peaceful protest will be the answer. However the against is why bridge a gap, that isn’t truly being filled, you are going up and hugging people but tomorrow their will be another incident.  By this I mean, the article I read was taking about people in Charlotte NC, who wanted Ken to leave because they felt like him walking around offering free hugs was him just giving up the “war”, that the police officers didn’t care about black lives , so why should they listen to what they have to say, they are hired to protect, but in their opinion, they are doing more harm then good. However he sees it as him just bridging a gap because all people in this situation are people too.  Relating to my topic of word aversion is because, even though there are messages of peace are coming out, people don’t want peace without action and justice. This aversion either to the word “cop” or the word “black” is what Ken is hugging for. This young man doesn’t care about what people think, and like I’ve been studying, aversion to specific word can be a serious issue,  it’s this idea that one person has more of a right then another, that is what Ken is hugging for, for all people to be seen as equal in this battle. However because of what is happening, there is a strong response when he shows up to events. Can a hug be bad?
