Kanoi: Of course Judaism isn’t always rigid black/white right/wrong! Even aside from the historical examples mentioned above, if that were the case, there would be no concept of halachic controversy (as there certainly is, even if you only look at the mishna and gemara, forget about other sifrei halacha), no concept of different legitimate paths of yiddishkeit, no concept of minhagim… there is plenty of room for a marketplace of ideas, even in Judaism (even if that may not be the best term, in context).
However, it did seem like PBA was bringing the term up in a secular context- for instance, like how my dad practically convinced me today that dictatorship is the only logical form of government. Logically, I know it isn’t. Emotionally, I know it isn’t. Ethically, I know it isn’t. But he was able to convince me, for those crucial three seconds, that maybe I was wrong and Stalin was right.
There is room for agreement or disagreement in matters like that, without it being for or against the Torah. And still, even in Torah, it’s often the best speakers (or writers of seforim) whose opinions were aired and adopted- think how many of the seforim we refer to were written beautifully, and how many poskim were also rabbanim, with influence and an ability to convince their kehillos and the local government of their positions. No doubt they were right in their opinions, but they had a much easier time of making their opinions heard.
