This is exactly what the speaker was pointing out if I am understanding correctly. Using bronze age texts as justification for your bullying is wrong and morally bankrupt. It is a perfectly acceptable lifestyle. Just as attending Appleseed shoots is a perfectly acceptable lifestyle. This point isn't being argued. You can express your views all you want, again, a point that isn't being disputed.
What causes you to believe that your beliefs have any particular value over those "bronze age texts" that have served as a moral compass for people for something like 4000 years? The fact that they've become politically correct over the past 20 years? The same could be said for Marx & Lenin's beliefs; they're still popular (although mostly in the US, it seems) after 70 years.
