“Second, the fact that gedolim don’t do it is a kasha on them, not on the techeiles.”
your level of apikorsus is exceedingly disturbing.
“it is a kasha on them” – WHAT?!?!?!? who do you think you are, better than gedolei torah? what do you know already?!
mods – this is a mitzvah – during a rabbinical meeting about the flatbush eiruv, one “rabbi” stood up and said Rav Moshe [ZT”L] is a rabbi and i am a rabbi. we disagree. Another rabbi immediately stood up and challenged him publicly and loudly – “how many prakinm are there in maseches eiruvin?” – the offending rabbi, needless to say, was silent. It is a mitzvah to stand up for the kavod of gedolim and assur to stand idly by while people dare disgrace them, kol shekain in public!!
