People misuse the word antisocial, just as you have. It doesn't mean not social [or friendly, or communicative], it means not exhibiting a social concern for the welfare of others.
No exhibiting a social concern for the welfare of others? Where do you come up with this stuff? I haven't misused the word at all, I've used it the same exact way it's defined in the dictionary. Granted, I only looked it up in the Oxford English Dictionary, and double-checked it at dictionary.com. I admit I didn't check the New Liberal's Dictionary for Redefining Crap, but I'd be surprised if it's not in there, too.
The instant I saw "exhibiting a social concern for the welfare of others" I realized what you'd done. You're taking the term "prosocial" and its definition (exhibiting a social concern for the welfare of others) and then jumping to "antisocial" as being the opposite, using the same definition with a "not" in front of it.
The terms "antisocial" and "prosocial" have very different word origins, which can't happen if they are antonyms of each other. However, "social" and "antisocial" are, in fact, antomyms of each other, and not coincidentally both have the same word origins.
"Prosocial" is an invented word born in the 1970s out of the new field of sociobiology developed by Edward Wilson. Wilson's sociobiology examined the social behaviors of organisms as motivated by their biology. Wilson and others have documented examples of “helping” in several animal species, supporting the notion that prosocial behavior is genetically predisposed. He didn't invent the term to mean the
opposite of "antisocial," since the word "social" already existed for that. He invented "prosocial" to specifically mean
exhibiting a social concern for the welfare of others, but more specifically, in the
precise context of
"characterized by helping that does not benefit the helper."
E.O Wilson has several books published, all of them fascinating. His book
Sociobiology: The New Synthesis caused a real feces storm when it came out in 1975. It brought Darwinian evolutionary biology into the the mechanisms of social evolution and social behaviors, showing that some social behaviors are hard coded in the DNA, so to speak. The book and it's notions were immediately lambasted by, like, everybody, as being a load of crap (the religious crowd literally crapped themselves over it - reducing humans to that of mere animals? Preposterous! ). His notions have since been proved correct.
Another book of his,
On Human Nature (which won the 1979 Pulitzer Prize, by the way), explains how different characteristics of humans and society can be explained from the point of view of evolution. He explains how evolution has left its traces on the characteristics which are the specialty of human species like generosity, self-sacrifice, worship and the use of sex for pleasure. The book is successfully completes the Darwinian revolution by bringing biological thought into social sciences and humanities. It and the other book mentioned above are two books which I cannot recommend highly enough. If you want to really understand humans and human nature, and how social behaviors work (and can be predicted), they're must-reads.
Fraternities are social in name, but quite antisocial in some of their traditions, behaviors, and their chosen recreational activities.
That's not true even using your own special definition of antisocial.
You can continue to say that hazing, binge drinking and rape culture [women are to blame for making men want sex, then refusing to participate, so they deserve to be overpowered] are social activities, but that won't make it true.
I've never once said that.
