shmoel:
We don’t discard a posuk in the Torah (fire and brimstone) because goyim use it in a messed up way.
Was I suggesting that…?
My point is while the concept of “fire and brimstone” is fundamental to goyish religion (as indicated by the original poster of this expression), there is little precedent to indicate that it is to ours. (The posuk merely coins the term. It does not refer to this concept at all.) Do you REALLY want to adopt such a system? (Especially since it seems to be working out SO well for them…)
