From Mobico:
“it is very difficult to have a dispassionate discussion with knowledgeable people on the subject.”
That by itself is a good reason to follow the Rema and only wear white tzitzis. The number of Aveiros one can get involved in by arguing unnecessarily are many and are D’oreisa. We are in Galus because of Sinas Chinam – not because of Techeiles. I fear that the individuals who wear techeiles might be considered Ba’alei Machlokes in Shamayim – even if they do it B’tzina.
