I am a Chassidic Jew and I wear trunculus tcheiles even though my Rebbe doesn’t.
My Rebbe probably doesn’t want to do anything different than his father, I never asked him.
I ask his advice about shidduchim, and minhagim and ask him for Brochos.
Many times in the Mikva I have seen others also wearing tcheiles and we give each other a knowing wink. (We wear a langge rekkel so we can’t know otherwise)
Because trunculus tcheiles is the real thing.
We know it.
The arguments against are so flimsy that it is hard to see anyone rationally accepting them.
Just because the Mizrachim accepted it first, is turning this into a political issue.
All I can say is that it takes a very powerful imagination to say that Chazal prohibited Kla Ilan because it so resembles tcheiles from some fish that was hidden away. While – at the same time – totally ignoring a snail (the persian word for a snail is chilazon) which was caught in the millions for dye and whose color is exactly like Kla Ilan.
So if you want to be an ostrich, bury your head in the sand. Or be worried about what will the other person say.
If you want truth and to be mekayem what the Ribbono Shel Olam asks us in the Parsha of Tzitzis, you can do it today.
The choice is yours.
