DY – I don’t think so. You may be partially right but not completely. I am saying this based on what I remember of the context of that post. I think it was in response to my writing that one must ask a sheilah before posting LH online about people who reportedly did some kind of aveirah.
There are many halachos involved, and it is not muttar to publicly shmear everyone whom you think may have done an aveirah.
Aside from the context, the bigger problem is what he wrote: he clearly wrote that he thinks that even if it’s an aveirah, he thinks one should do it.
Where you are right is that probably where he was coming from was: it is obvious to him that in the specific scenario he described there is no sheilah since it is obviously permissible to say something!! And if the Rav asked says it’s not, either he misunderstood the question or he is mistaken, and of course you should ask someone else. And it’s possible that it’s not necessary to ask in the first place.
But that is not because there is anything more important than halacha. It is because that is the halacha in that particular case!!!
But l’maaseh, that is not how he phrased it. Perhaps, he didn’t mean it that way, but then he should clarify because the way it’s phrased is problematic.
Also, in the context, it was problematic in any case. In this example, it may be obvious that it’s muttar, but there are many, many cases where it is not, and that is why a sheilah must be asked. Especially since the context was about shmearing people online not about a private conversation with individuals, which is completely different.
