If you hate the Shaoul's so much, why do you live in their buildings? Isn't there something inherently stupid about putting money in the pockets of of a man you so viscerally despise? Maybe I'm just a different kind of consumer, but when I disagree with a company's service or its political views, I simply go elsewhere with my business. Rent is no different. If my building owner was an anti-Semite, I'd choose not to live there. Furthermore, if people didn't want to live in their buildings, they clearly wouldn't be very successful.

New York is an expensive city, there are no God given rights to live wherever you'd like for whatever price you'd like. If you can't afford to pay market rent, why should you be there? Does that work for you at the grocery store? Can you just ask to pay less because you feel like it's your right? Perhaps if you spent the same effort working as you do with your community action boards, you might be able to afford the rent. Have you considered the ridiculousness of trying desperately to fight for the right to live in a building run by what is in your mind an evil slumlord. Why don't you just leave?
