yiddish was the language of the gedolim.for that alone it was important as a means of communicating with them and understanding thier daas torah…today this reason is not as relevant.the chasidim use it as a buffer against integration and influence with society.it is also an issue of minhag avoseinu .(RAV SHACH ZTL advised the mir elementary school to retain yiddish as the language of instruction for that reaon) to flippantly compare it to spitoons and the like is plain arrogant
