Okay. I will try once more to go through this for you step by step.
R’ Yonasan let his Tzitzis drag on the floor in a cemetery. R’ Chiya asked him how he could let that happen, it’s Lo’eg LaRash. R’ Yonasan replied that the Meisim don’t know what’s going on so there’s no Lo’eg LaRash. Now, clearly both of them hold that there was no problem with the Tzitzis being on the floor in general, because if there was either R’ Chiya or the Gemara would have said so.
How is this not a Ra’aya B’rurah that it’s Muttar?
