Like that guy that had sex with a gator, or anti-vaxxers, or anything else where someone was being stupid and it is endangering lives. The gene pool is trying to self-cleanse. Think about it. If that gator had bit off that guy's dick, he wouldn't be able to have kids. Therefore, no gator-fûcking genes would be passed on. Anti-vaxxer's kids might die from diseases people with common sense have no worries about. No kids, no genes passed on. Just let natural selection run its course.
