Which ones are those? I'd imagine the HOAs have some "protections" written in. I'd guess they're reasonably close to the effectiveness of local government "protections".
Suing for first amendment rights, property rights, inability to tax without voter approval (in some states). Whereas HOAs are not covered by the bill or rights and can levy special fees by a simple board vote typically.
HOAs are covered by the bill of rights. See how race related deed restrictions have been removed. All it takes to raise taxes is a simple vote by your representatives.
Actually no... They're not covered by bill of rights and regularly infringe on speech. Race protections are due to federal housing laws, not the bill of rights.
Also, the bill of rights has nothing to do with race and doesn't make any mention of it.
