What it does do is use a cartooning style that seems similar to the cartoons one might find at the dentist about why you should always floss your teeth or the cops hand out about why you must never talk to strangers. Thus it is somewhat ironical in the cartooning style it uses. I admit that someone could find this tedious but other people can admire it as a stylistic conceit (although admire is maybe too strong a word )
But I'm curious how you see it.
You have to pitch things appropriately. A six year old who has just noticed that some of her contemporaries have penises and some don't probably does not want a diatribe about Trans Exclusionary Radical Feminism and if she's wondering about TLS she probably doesn't need an excursion on ECC Safe Curves, but with care to stay relevant and not just blast her with jargon she doesn't understand there's no reason any topic needs to be off the menu.
Yes.
ps: I find it insulting that you find a random illustration insulting. Re-asses your thought process, I'll wager a guess you're better than this.
I honestly have no idea what kind of adult thought process is okay with being treated like a 6 year old, as this comic attempts to do. I honestly am better than that - but it sounds like maybe you're okay with it??
