Soliek,
I just realized that I missed a post of yours from a few days ago:
DaasYochid: your and everyone else’s raaya rom whisket and beer is invalid because those were categorically paskened on by eminent rabbonim. its not that people stam paskened themselves that these items are categorically kosher…its that they were given a PSAK that these items are categorically kosher
There may have been rabbonim who were mattir many products in those days. I was not addressing the issue of following psak, I was speaking about the inherent kashrus.
