SQUARE_ROOT:
Your call to Star-K and their answer that they never heard of it does not therefore mean that I lied. I did not lie. It simply means that they never heard of it.
I did in fact hear that directly from a world-class talmid chacham. But all the gedolim anyways said the same in their writings, as mentioned. The Chazon Ish himself has in his Maaseh Ish that an apikores nowadays is one that either celebrates the Zionist “independence” day or one who blames the gedolim for the death of the Jews in Europe. So you can take all that to the STAR-K, if you want. But the greatest gedolim have stated this repeatedly.
