Many carbohydrate-containing foods cause gas and bloating (vs. fats and proteins, which produce very little gas). Starch containing foods such as corn, noodles, pasta, potatoes, and wheat, also produce gas.
SJWs are people for whom activism is an activity, like shopping, or being on a sports team. They bond with one another over having the right opinions. Cheap and easy, with no chance of criticism from others, social activism provides a hobby to talk about at the local bar after a long day of work.
A big chunk of their activism depends on subjective feeling and perceived value of the parties involved. Before an SJW can make a decision on what is right or wrong, she must first know the race, gender, and sexuality of the involved participants so that she can decide whether or not to be outraged. A statement or idea in isolation is not enough for them to come to a conclusion on the acceptability of a statement.
