People are not forced to treat EA as an all-or-nothing package. If some of their claims are more convincing than others, and acceptance of only the more-convincing claims leads to SBF-like behavior with much-higher-than-background probability, it is important to strengthen some arguments, and/or withdraw community support for ideas that are currently too unsafe in practice.
I agree with this. I think there are two sides of EA - the futurist utilitarian viewpoint and the rational QALY/$ viewpoint. I'm a believer of the latter, but do worry because this is boring (malaria nets and deworming) the former is the only one people hear of or see even if it's a minority group.
