I wasn't speaking about the specific case at hand in that sentence but the general opinion.
I think that the gemera's example of a chasid shote is specifically and intentionally a life and death situation.
Did I say I was quoting a gemara?
In that case, I would also generally be machmir.
The definition used comes from there.
Someone who is machmir would in this case get away with the bare minimum and definitely not use 2 hands, but somone who is in general meikil I do not see it as a big deal that he used 2 hands.
On what basis?
I would say to refuse the first lady's hand shake and risk embarrassing in public a president known to have a fragile ego would make one a chosid shoteh.
Possible, but to say that that was what led him to shake may be quite far fetched. One would need a really clear conscience to make these calculations at the spur of a moment like that.
Or to have anticipated the possibility and thought about it and made a decision beforehand.
Still on hold with sears.(The 70, is hours not min.)
Thats why its called HUCA.
Keep holding. Someone will be right with you.
