What's really interesting is for the people at BDO who have hate, is that they wanted to create Thought Crimes.
1. For a gang color to be a legal gang color, there has to be a legal conviction of a gang, a criminal conspiracy in which those charged and convicted all wear the same gang colors. Such a criminal case is not on the records.
2. To outlaw Thought or Images that may be associated with those thoughts is what the USSR would have done, and they killed 62 million people, poets, writers, musicians, artists, dissidents, to do that. It didn't work.
3. If the hate mongers at BDO wanted to ban a symbol associated with mass killing and therefore negative "hate", they would really have to start with Che Guevara and the Hammer and Sickle of Communism which killed more musicians, poets and political dissidents in the last century of than any other system known to humankind.
In conclusion, the hateful people at BDO did not apply intelligence to their assessment of ways to better the concert going experience.
Limiting alcohol would the the most intelligent way to improve the Concert Music experience.
