I have many times seen what appeared to be disrespectful pushing and shoving to get to kiss the Sefer Torah or the rebbe's hand. When inquiring about it, I was told that it shows devotion to the Torah (or the rebbe), and that it does not constitute transgression of otherwise quite obvious mitzvos (both positive and negative commandments).
What does Hashem want more, propriety or devotion? Where do we draw the line?
Inspired by this comment.
