if you still maintain wahtever explanation you concoct
The gemara means exactly what Sam2 said it does.
Do you really think I was saying that the rule is we are always machmir? You can’t bring proof from specific cases in which we are meikil; of course we are sometimes meikil. We are also sometimes machmir.
Bringing “koach d’heteira odif” to support being meikil in general is wrong, and dangerous. In fact, as Sam and I have pointed out, that gemara actually indicates that unless one is certain of his position, he must be machmir.
