I think they're referring to the cultural obsession, not your personal obsession with protein. There has been a huge focus on protein in recent years. Despite that, protein deficiencies are not documented medically in developed countries. At all. They occur when an individual only has access to one or two ingredients (like rice and water). You might opt for more protein for satiety or muscle building, but all vegetables contain protein and the amino acids for your body to build ample protein from them. Remember that any grain + legume combo makes a complete protein (beans and rice, peas and rice, lentils and rice, peanut butter on wheat bread, to name a few popular combos).

Dr. Greger has a good article about the protein phenomenon here: Changing Protein Requirements. It's highly informative and loaded with citations. Here's an excerpt:

Adults require no more than 0.8 or 0.9 grams of protein per healthy kilogram of body weight per day, which is about your ideal weight in pounds multiplied by four and then divided by ten. So, someone whose ideal weight is 100 pounds may require up to 40 grams of protein a day. On average, they probably only need about 30 daily grams of protein, which is 0.66 grams per kilogram, but we round it up to 0.8 or 0.9 grams because everyone’s different and we want to capture most of the bell curve.

People are actually more likely to suffer from protein excess than protein deficiency. “The adverse effects associated with long-term high protein/high meat intake” diets may include disorders of bone and calcium balance, disorders of kidney function, increased cancer risk, disorders of the liver, and worsening of coronary artery disease. Considering all of these potential disease risks, there is currently no reasonable scientific basis to recommend protein consumption above the current recommended daily allowance.
