I wouldn't hesitate to make my AME understand how uncomfortable and distracted any helmet would make me. Having obtained a 'line' from the AME excusing me from wearing a helmet, if my employer were to try dismissing me I would involve BALPA and be pleased if the press were to get involved.
This would probably alert offshore workers to the safety issues raised by potential distraction caused during flight, due to being forced to wear something which could be likened to wearing a hair shirt for some pilots.
Once again, nobody is advocating that this should be compulsory, we are simply discussing the pro's and con's, and whether or not it is a good idea and should be made available. Your comments are highly divisive and intentions damaging with reference to "alerting offshore workers" and "involving the press" in you last statement and i would caution you against such action based purely on your own subjective opinions toward safety.
