So, if a teen who has attended “comprehensive sex education” gets pregnant, that is proof that “comprehensive sex education” doesn’t work?
However, if 47 countries try socialism and 47 fail, that is NOT proof that socialism doesn't work.
If fifty convicted killers are paroled and all fifty commit another murder, that is NOT proof that rehabilitation doesn't work.
And, if the Top 10 most expensive school systems in the country also happen to be the Bottom 10 worst performing school systems in the country, that is NOT proof that we don't need more money for education.
