That's completely idiotic. Communities are completely within their right to dictate terms of their community. If prospective owners don't like the rules, they shouldn't purchase.
If the rules are put in place pre-sale, with the agreement of the owners wishing to sell sure..
My problem is that communities change the rules with out the consent of the property owners. I do not believe in Democracy, I do not believe that 50.1% of a community has the ethical right to impose rules on the other 49.9% of a community
