I'll fly IMC without radar on occasion and done in such a way as to minimise the risk. It's difficult to say that it's more dangerous than joining the circuit in good VMC when everone else is doing the same thing and ATC have lost the plot. It *may* be more dangerous but I'd challenge all of these people who religiously perceive it to be more dangerous to back up their perception with some facts.
On the other hand, the more of you that think it's too dangerous and won't do it, the safer it will be for me when I do.
