Well, bad news. The same forces that conspired to make original rituals more complicated, and old practices more expensive, have set their sights on Purim Katan, the minor holiday that falls on the 14th day of Adar I. For ages, the only rule for the day was no fasting or signs of mourning. Simple right? Well, my money says that within the next twenty years all that will change. Why do I say this? Because this year Twitter is telling me about Rabbis who've this year ordered their flocks to send shloach manos, and people who made seudot. This time around these extra practices aren't "required", but that's how all the insidious new customs start. I assure you no-one thought an upshurin was "required" at first either; now if announce that you plan to skip it, your frumkeit gets questioned.
Here's how this happens:
Insane and insecure people start doing something for insane or insecure reasons.
The children of the original insane and insecure people pass the thing to their own children because its what "our ancestors did." Rabbis start to yell and protest.
Year 25 and on:
The effect snowballs as insecure people see other people doing something that looks frum, and want in. Also, the new thing catches on with well-meaning people who "want to be on the safe side", or say "it can't hurt." Rabbis become reluctant to yell and protest but some brave ones continue to complain.
A genius Rabbi invents a religious justification for the insane and insecure thing. [With upshurin the retro-reason relates to how we can't take fruit from trees for the first three years, and a verse somewhere that says men are like trees. Not making this up.]
Even though the new thing caught on from the bottom up, Jews who know the new thing is a new thing start pretending that it was actually imposed for "reasons" by the Rabbis. Other Jews start to deny that the new thing is a new thing, and instead discover elaborate proofs that the new thing was observed thousands of years ago. [According to the Hasidim Moshe had an upshurin. Not making this up either]
The new thing has become mainstream! All the angry opposition voiced by halachic authorites against the new thing has died out.
Someone on Twitter (you know who!) says those halachic authorities who opposed the new thing "are not from our mesorah" and insists that the new thing was created for a reason by rabbis who carefully followed the precise halachic guidelines known to us today.
