Wolf,
There are a lot of people who “lip-sync” during Simchas Torah, either because their voices get tired, or they aren’t sure of all of the words of the song, or perhaps for your reasons, yet they still want to participate as much as possible.
Are you therefore to say that all of these Jews do not merit the Shechina’s presence? What’s sauce for the goose is sauce for the gander. Don’t give us the “this only applies to me” stuff. Sheker is sheker, no matter who does it.
As someone who has lip-synced during Simchas Torah for several of the reasons I mentioned above, I am bothered by this trolling thread.
