Typically the commandments make sense on more than one level. Dietary rules prohibited things that were common pagan sacrifices. Since all eating is a sacrifice offering to God, it was considered a safeguard against confusion with pagan practices. Its relative importance can be seen by the prescribed penalty for transgressing (to be put outside the camp and be ritually unclean until evening).
You’re treating God like Someone who is throwing dice in a corner then daring you to match what He just threw. Rather than Someone who is offering to save your souls in love. You’ve created a need which isn’t even there except in your desire to be dignified.
Agree to disagree? We believe that the world was instructed by G-d on how to live and how to make it into a G-dly dwelling-place. 613 commandments for Jews and 7 for non-Jews. You believe something different.
You see dietary law to differentiate from pagans only. We don’t refute that, in fact our scholars have codified that...and there is a deeper level still.
Imagine if G-d spoke to you, HiTech RedNeck, and said, HTRN, please dig a hole for me, then fill it in. Would you balk at the instruction of fulfill His will? Jews know what G-d told us to do. We follow everything (optimally) with joy and love. Imagine to be commanded by the King of Kings! If your experience with Jews and your study of them doesn’t reflect that, I don’t think it can be changed—nor need it be.
