It’s still not an appropriate comparison. Taco Bell is junk food. Americanized Chinese food (or Mexican food) is not at the same level unless you’re intentionally using that term as a pejorative.
Your equivalent statement about Mexican food would be that you assume Taco Bell is what most Americans are eating as Mexican food. That doesn’t seem a valid assumption at all - maybe for a certain demographic (e.g. young) that’s true, but I’m very skeptical that such a claim would stand up to scrutiny.
Similarly, you cannot group the corner store (nominally) Chinese restaurant owned by a Chinese (or as likely in much of US, Korean) family as being in the class of highly processed, pre-made food as Taco Bell. Sorry but no.
American Chinese food is a lot sweeter, thicker, and more soy sauce based.
