This part:

"Know-it-all / hipster Probably studied philosophy, english, film-studies, or engineering."

should cause us to remember this:

https://en.wikipedia.org/wiki/Ad_hominem

"An ad hominem... is an attack on an argument made by attacking the character, motive, or other attribute of the person making the argument, rather than attacking the argument directly"

We should remember, when we see an argument that starts with such a lazy use of a stereotype, there is a good chance that we are looking at a bad argument.
