I think the thing that you're not getting is that it doesn't show emotion. It might, to you, but it's not inherently emotional.

This is a lesson that i keep learning over and over again in life through my various amateur creative endeavors (music, writing, art etc)...just because you feel an emotion when you're creating something, doesn't mean that that emotion is somehow magically conveyed. This is cringingly obvious whenever i read old writing or listen to old music...i remember the emotions i felt at the time but, often, none of it comes across with fresh eyes.

If you want to convey an emotion, you'll have to figure out a method to creatively help people adopt a frame of mind, which then allows them to be receptive to your subsequent message. Cursing out of the blue isn't enough to do that. It's jarring and cringey, and you (or him) will look back on it in 5 years and realise that.

It doesn't/shouldn't take away from the main content of a presentation though.
