All I am saying is that it's safe enough for a kid to do if you think s/he can handle a bike to begin with. I do think it is condescending to presume that other parents aren't as responsibile as you in terms of parenting.
EDIT: I also said bikes themselves are inherently dangerous. I think kids can ride bikes but I wouldn't take issue with a parent who thought it was too dangerous. What I do take issue with is arbitrarily drawing the line at FGs when plently of people rode them as their first bike.
