Well, humans require fewer than 5% of calories to be derived from protein, that's about 50-60g for males and slightly less for females. You could eat 2,500 calories of only fruit and still get enough protein. But not B12, that requires a supplement. The sources you mentioned are high in protein, but I would argue they aren't necessary for a functional vegan diet.
Running Room, Livestrong, MyFitnessPal, countless other sites, my running clinic leader, the sports nutritionist at my running clinic, my doctor (certified in sports medicine) all recommended between 80 and 100 grams.
You really don't know what you are talking about do you?
A couple of for profit blogs and people without a nutrition education inform you. Sad. Check any reputable source, like WHO, you are eating too much protein, dude.
