@UJM, “Personally, I wouldn’t want to have a belief that many shittos would deem the person an apikorus — even if according to another shitta he wouldn’t be deemed an apikorus.”
This is what we call a bad argument. I am absolutely certain that I can find certain things you do that would be deemed apikorsus by somebody….
To borrow from another thread, anyone who davens with a chassidish havara, and prononounces words in ways that change the meaning may have never davened in their lives… Again, according to some shitos, and why would you take the risk?
Do you daven “Rabeinu Tam”? As in, the made up zman of rabeinu tam of 72 minutes in NYC? DO you know how many shitos there are that would consider every mincha you’ve davened after the zman to be a tefilas shav? It may not be your shita, but why take the risk? I wouldn’t want to have that belief….
I can go on for hours.
