Abba, if this is how you go about seeking support for a cause then please do it somewhere else. I don't care for your attitude.
I have hunted in NYC myself with the use of a permit. The stipulation is that there are certain parks that are off limits, Central Park being one of them, but there are still many parks and other sites open to us. Is it right for the city to exclude certain public parks? No, I don't believe it is, but it is their prerogative, and perhaps based on the bad habits a few detectorist have demonstrated.
Yes, the metal detecting community can and should voice their concern and frustration at such limitations, but just because folks here, and perhaps at other forums, don't necessarily immediately jump at your announcement does not give you the right to be rude.
