Great discussion, I have made some points in my recent post.
As long as we can talk openly and honestly about appropriate risk mitigation, I think we are on the right track. We set speed limits to driving, not outlaw it. Condoms are recommended for those who engage in certain types of risks. Antiseptic treatments I think are an important part of pre-surgery procedure, though we could have a really good conversation about how preventionary treatments is leading to antibiotic resistant strains of certain diseases.
A good place to start, in my opinion, would be to admit that risks are not 'one size fits all', and thus invite additional levels of analysis over and above: 'There is a risk, so stay inside until its passed no matter your current conditions'.
Maybe someday we will hehe ;)
