I lived in Park Slope for many years. I was active in the art community before we got pushed out by the realtors and yuppies. I remember when people wouldn’t walk down 5th Ave and it was recommended not to walk or live past 6th. Like many groups that take over a region they come with their own set of standards and values. It’s interesting to see the realtors fight with the community, since they worked hand in hand to completely gentrify the neighborhood. Now there seems to be an difference in ascetics.
I think people who try to eradicate other cultures and believe systems should try living in a region where freedom to express oneself is punishable by death, or worse. I say keep the mural and don’t give in. I don’t think it will cost the realtor sales, just more attention and perhaps a little aggravation. But there is something to be said about street art. It exists and always will, no matter how hard people try to get rid of it. And it’s important to remember that art chronicles the times in which we live. And we are living in some pretty weird times!!!
