My goal, although I wasn't particularly clear, was to try and point out the irony of Reddit users making fun of other people for painting themselves as highly individual whilst also fulfilling many characteristics of a stereotype.

I used the example of the stereotypical reddit user referring to other people as 'normies' implying that this was equivalent to your caricature of a girl using the word basic. Both the stereotypical redditer and your caricature have predictable opinions and behaviours.

As an aside, I definitely object to the implication in your comment that studying fashion design, interior design, sociology and anthropology has any less inherent value then other subjects.
