My apologies for that, you are right (in this case) it was uncalled for.
However it is impossible to have a sensible argument with someone who will not compare apples to apples and throws in a melon every so often.
Unfortunately the debate is always going to be like that.
The prime example is the bang your head against a wall with a helmet and it hurts less than without "experiment to prove that helmets should be worn.
This is frequently put forward, but the problem is that it proves absolutely nothing. The experiment works for pedestrians, but that is unacceptable for discussion.
Cynically wearing a canteloupe will also have the same effect
The "experiment" is proposed as "proof" that helmets work yet despite the same successful result it is no longer valid as proof for pedestrians, or that wearing fruit is beneficial.
Equally the emotional blackmail of "wear a helmet or be in a vegetative state" applies to any head injury, not just cyclists
Finally look at the attempts to restrict debate to set areas... again limitations that are more about excluding uncomfortable arguments than any real question over validity.
It is a wide and open area for discussion and the evidence points in all directions. The questions need to be asked.
