I have no strong opinion on the techeles issue at all, but what I find fascinating here is that the pro side is talking like they were raised locked in a basement and only shown the pro-techeles shittas so that it’s absolutely shocking when people assert that rov poskim are opposed.
Also, a video of Reb Chaim saying “if you had the real techeles you should wear it” as proof? Come on… That’s beyond a loaded question. That’s like asking “if you knew for a fact that this batch of chalav stam milk were actually pig’s blood died white, could you drink it?” And then using the psak as a proof against all chalav stam.
