I think there is another facet to this statement: “…a majority of the things that we find wrong with other people really stem from things that are unsatisfying about ourselves.”
When tragedy strikes, we are given “permission” to express ourselves in light of it. However, some groups and individuals take advantage of that “permission” in order to highlight issues that discontent them. We make an opportunity out of a tragedy in the name of some issue that discontents us–we “proof text” the situation, if you will. Gun control folks are going crazy right now. Issues of immigration and individual rights are coming up.
Is it appropriate to raise these kinds of questions? (the real question here is is: are these things the cause?) Is it appropriate to raise them today?
