ujm- Yaakov: You can read for yourself what the Steipler Gaon said in high praise of the Neteurei Karta, as written in קריינא דאיגרתא, and directly quoted above in the Opening Post of this thread.
I read it, as did Yankel Berel and everyone else…
The first thing I wrote on this thread seems to have slipped under your radar, so I will repeat it here:
There is a teshuva in Teshuvos HaRashba that says that the butcher store located at a certain address in Barcelona is certainly Kosher. If you happen to be in Barcelona, you know where you can go to pick up Kosher meat with the Hechsher of no less than the Rashba himself…
Now, try and think about the connection between the letter of the Rashba and the letter of the Steipler… And why it is ridiculous to take letters of Gedolim from generations ago and cut-paste to different people in different times doing different things, even if they happen to go by the same name.
