I saw a news report about how people put Confederate Flags on the grass outside a black church in Atlanta. The black compared it to "swastikas at a 'Jewish temple'".
If this was an act of graffiti, it would be a hate crime, but they just put a Confederate Flag on the property. No damage was done. If the blacks don't like it, they can throw it away. It's like if missionaries put missionary material in my mail slot, I rip it up and throw it away.
