As if.....

These are all gringo affectations. Authentic tacos are very
different. Picture two small corn tortillas, deep/pan fried in lard
until pliable, then paired together and folded, then filled with a
prepared meat such as cabeza, carnitas, birria, etc, and topped with
finely chopped onion and cilantro. None of that burger meat, cheese,
iceberg, and tomatoes nonsense. Gringos call them "soft" tacos.
Mexicans call them tacos.

Granted, these are NorCal-style Mexican tacos, but they are more
authentic than those hard/crispy pre-formed corn taco shells filled
with Taco Bell ingredients. One thing is sure, I've never EVER seen
any taco made with a flour tortilla.
