Unless you already know each other and this is a continuation of a private dialogue, that’s a pretty aggressive response to a throw-away line used by vast numbers of pig owners! In context, I took that phrase to mean what we all do in terms of garden and vegetable waste, particularly as MissEllie is clearly clued up about the regulations relating to pig-keeping.
Certainly the law of the land must be observed, but I think there is also something along the lines of “innocent until proven guilty” in the concept. If you’re really concerned that there is a major breach of the regulations, Fenris, why don’t you ask first and shoot later?! Otherwise we’ll frighten off all first-time posters, as they’ll be nervous of attracting censure and ridicule.
