~くらいで (just with, dismissively)

The scope particle くらい/ぐらい combined with で, dismissively downplaying the cause — '(just) with that little X / for such a trivial X.' Used when the speaker feels the cause doesn't justify the reaction: この程度で泣くな ('don't cry over this much'), 一回失敗したくらいで諦めるな ('don't give up just because you failed once').
