Why is Comic Sans hated more than that font?
Because Comic Sans is more widely used, and it looks like something your kindergarten teacher uses to send out newsletters to parents about the upcoming PTSA school canned food drive fundraiser. It's insipid and looks condescending.
That font is pretty shitty too, though. I'm happy I don't have it on my computer. It looks like the kind of font used for Tex-Mex restaurants trying to look "authentic," and seems to remind me of playgroups for toddlers and infants for some reason.
