The quasi-anonymous "CLS", 'blogging on Classically Liberal, reports on a complaint brought to a Neptune, NJ residents' association meeting about "flags being displayed...declaring the occupants' sexual orientation or proclivity — not just the multicolored "gay' striped flags, but also banners indicating fetishes and or other "lifestyle' choices."
No such thing, but I'm reasonably certain that a good marketer could sell them. "Hmm...the frotteurism people don't have a banner yet...and what about the guys who like old-fashioned stockings? And a box of the special lolicon pennants are ready for shipment to Japan!"
Not my line of work, but I wouldn't be surprised to see these appear, thanks to a suggestion from a New Jersey busybody. Ahh, the beauty of the Internet Age!
