Is breathing kosher.

you are defending this rabbi for who you think he is, a rabbi, and not for what he said, which you admit that you don't enough about. that is called "prejudice".

Just buy a kashrut stamp and pay the tax to the Rabbanut. This hair splitting controversy is a mere financial matter.

the oral suction applied by some mohels after Brit Milah, that's just fine, right?

I mean you don't sneeze or cough on someone else, or breathe on them either really... And then of course muttering curses would be considered sorcery perhaps. Thou shalt not suffer a witch/sorcerer to live!

by the Rabbanut. The Rabbanut has a test called "Smicha" that certifies that a person can be a Rabbi. A law must be passed that only people who have Smicha from the Rabbanut can call themselves and work as Rabbis.

This is not new news. In Nisan of 5768, the greatest poskim and roshei yeshiva of our generation issued a Psak Din that all shaving machines which leave the face smooth are halachically equivalent to a razor (not because the uproot the hair, but rather) because they do not leave over any hair. The Psak Din cites that this was the opinion of the Chofetz Chaim (in whose time shaving machines were invented), the Chazon Ish, the Steipler Gaon, Rav Schach, etc. The Psak Din was signed by 34 poskim and roshei yeshiva, including Rav Elyashiv zt'l (who wrote that today's electric shavers are much more severe than the hand machines prohibited by the Chofetz Chaim), Rav Noson Tzvi Finkel zt'l, Rav Michel Yehuda Lefkowitz zt'l, Rav Aharon Leib Steinman shlita, Rav Shmuel Halevi Wosner shlita (who attested that this was the opinion of the Chazon Ish), Rav Nisan Karelitz shlita, Rav Chaim Kanievsky shlita, Rav Shmuel Auerbach shlita (Rav Shlomo Zalman Auerbach zt'l wrote that all close cutting shavers are an "issur chomer").
