I think it would be more accurate to say that the WW as presented in the books is condescending, arrogant, and profoundly ignorant (not to mention incurious and unimaginative) about mundane society, science, and culture. (Interesting how easily JKR presents that without meaning to.) They have no idea how the mundane world works and don’t care. It’s very likely that this will come bite them in the arse in years to come as cellphones and the internet make their terrible approach to the masquerade untenable.They also view muggle tech as crude, primitive and beneath them. But main thing is, HP is kids/young adult book series. Factor in that guns are that big culturaly in uk or europe in general, and it's easy reason why no one uses them. You also don't see anyone using cell phones ( Nokia 5510 was big in 98) or telephones, no kids walking around with GameBoys or walkmans (which is something one would expect in school in that era).
