Err, I don't think so. What I quoted said "People who are X do not do Y". The contrapositive of that is "People who do Y are not X". And I disagree, because I know people who do Y and are X.
You are conflating quantifiers here. "Pretty much universally" is not a universal quantifier, it implies "there exists people who do Y who are X." So, your example of "there exists people who do Y who are X" doesn't contradict the original statement.
time_management says "in my experience" so unless you can produce a universal quantifier for your claim, or do some sort of analysis to define cardinality, you can't invalidate what he said.
A universal quantifier is absolute. Actually, it's a pedantic point.
The better point for tm to claim is most chaste women are moral, whereas the same cannot be said for unchaste women. So, to guarantee a better chance of developing a relationship with a moral woman (i.e. more likely to not commit adultery and be temperate), we men should be chaste and look for chaste women.
This is probably what he intended anyways, since it makes more sense.
I don't think you've read the rest of his comments. He absolutely meant what he said, and he meant "pretty much universally" as a universal. Sad, I know.
No, it's not a logical fallacy. time_management has said over and over again that quality women do not do X. Not that women who have the quality of chasteness do not do X.
The quote states that "people with quality X tend to not do Y." This does not automatically mean "people without quality X always do Y."
