Facebook’s flawed logic on political ads

Zuckerberg’s logic on not fact checking political ads seems to be that Facebook will leave it to other parties to do so. This logic might seem to make some sense, but ignores the way Facebook actually works. Individuals end up biasing the inputs they receive from Facebook by choosing the individuals and services they follow. If most folks targeted with an ad tend to agree with the sentiment expressed, accurate or not, how would responses to such ads generate much in the way of pushback. If Facebook is not going to ban political ads or fact check political ads, perhaps it would make the most sense to not allow political ads to be targeted. If viewed by all, all would have the opportunity to respond.
