I believe we're arguing the same point. Advertisers are the ones who do the targeting and even with the tools Facebook provides, they make terrible targeting decisions. It doesn't matter if good advertisers use it properly, the majority do not. If Facebook don't prevent these poorly targeted ads then they can't guarantee any level of targeting at all on their site. This means that users are desensitized to the ads shown there, decreasing their value as an adspace.
