Neither does your swearing.
Fred,
You are confusing or mislabeling Expletive Infixation with swearing. ‘Grow the fuck up’ is not insulting anyone growing up. It’s intensifying the level of growing up that must take place.
In certain cultures and socio-economical circles people choose to mislabel expletive infixations as swearing as a form of diminishing the validity of the values being expressed. It’s what I would call: condescending af. I really hope this is not the case here. Is it?
Macs SUCK! I just prefer them. Ponder that one…
You missed your calling in academia.
