I don't think anyone denies that there is often crime and violence in Flatbush, Brownsville, Crown Heights, and other neighborhoods around the parade route. In particular, it's a stretch to assume that everyone giving you downvotes "doesn't want to accept reality".
For my part, I wonder about the most effective way to reduce incidences of violence in our community. I know that these are some of the neighborhoods that have systematically been denied investment, perhaps that has a part to play? Also, these neighborhoods have experienced the brunt of overpolicing in our community for quite a long time. Somehow I don't think that the answer is more police. I don't think the answer is normalizing this appalling and illegal move.
