There is a physical reality to the third law. The arrow that hits something can get splintered, the bullet deformed, the hammer bounces back off a wall, if you punch someone you can break your hand etc etc.

These engineers are disagreeing with you because they use this law when they do free body diagrams -- if you don't put in the reaction forces, it won't match reality. This is how buildings, structures, mechanical systems etc are designed, it is definitely real.

I honestly think you should delete that part, because my takeaway is, if I can't trust his reasoning on the stuff I understand such as Newton's laws, then why should I trust him on the things which I don't understand, such as relativity? I don't want to be mean, this is just how it comes across to me. I think alternative physics theories are great because clearly there are issues with the current theories, keep doing what you're doing :)

Newton’s Third Law may not fit your macro model of the universe, but it’s never once let me down for engineering purposes.
