Ravingdoll,having lived in Mexico for 17 years, and travelled throughout Mexico, I am offended by your idea of what Mexican is.
Actually what you have described is some ugly image of Mexico perpetrated by Americans.
Frida Kahlo is an icon here. Some of her stuff is weird, some springs from physical pain.
But she and Diego Rivera were revolutionaries, thinkers and artists.
Cacti in pots and sombreros are not kitsch, they are sully slurs. This themeis something you would find in New Mexic or Texas.
Your idea is almost as bad as wearing a fruit basket on your head a la Chiquita Banana, another American not-so-friendly caricature.
White on white embroidery, or the colorful embroidery of Oaxaca is Mexican, gorgeous and fitting.
Would you paint your face black with big white lips minstrel style if you were invited to an African themed party?
Mexican cuisine was named one of the fine cuisines of the world by UNESCO.
I hope that there is guacamole served as well as pico de gallo, and chiles rellenos, or tacos al pastor, accompanied by fine Tequila, good Mexican beer (Corona and Pacifico are NOT good Mexican beers). How about a rich, dark mole? Or even some fine Mexican wines from the Valle de Guadalupe.
Caricatures as you have described as kitsch are not cute or funny. They serve to dehumanize .
