Surveys about how think are always slightly pointless IMO. How about some facts?
Rugby needs to be very clear about the difference between the top levels of the sport & the amateur grass roots game.
Junior & low levels of the game do not see significant brain injury problems. Rugby is probably safer than at any time in its history, but you do not see large numbers of old ex players propping up bars with concussive brain issues. Fingers that don't work, wrecked ears & ruined knees, yes, but dementia, no.
The issue is at the top of the game & revolves around multiple head injuries during daily training & weekly games. The vast majority of rugby players are never training nor playing at that level of intensity so won't, as a general rule, encounter the same issues.
Its like fiddling with scrum rules & tackle heights, the vast majority of rugby players had no issues with existing rules but they needed to change at the top of the game.
