play partner started quoting jordan peterson post-coitus... what would u have done

so... finished a really good session, lying around chatting, husband from the other couple starts going off on "responsibility" and "chaos" and "the masculine principle" and i realised mid sentence ohhh u are one of those. my partner was trying not to laugh. i didn't kno what to say. did i miss a red flag in his bio. should i have called it out. should i have just laughed. ppl who've been in a similar situation pls share how u handled the post-shag philosophy lecture...
