Anyone can pull an abberant psak out of a hat to prove alomost whatever they so desire.
Ironically it’s the same “crowd” which claims from the other side of their mouths, that halachah doesn’t take place in vacuum.
What were the circumstances?
This world does have a goal!
Will it bring it closer?
Every factor must be weighed
Or do you(plural) pay fealty to a modified version of ‘when there is a halachic will there is a halachic way’ ?!
p.s.Therefore it is utterly ridiculous,and rather revealing, to claim or feign that any earlier great posek would be out of the present mainstream
