There seems to be a trend among those who are interested or uneducated in feminism and other social justice movements. This need almost always comes from those who are from the majority (thus, generally white, straight, cis men) who feel that they can demand education from those who are knowledgeable in the subject. They get angry or upset when someone refuses to educate them or does not want to answer their many questions.
Often, the questions that are asked are easily answered via Google. There are many, many 101 courses that people have written to cover these questions. Many people have to answer the same questions, repeatedly, and it can get quite annoying. For example, I often get asked what the asterisk in trans* stands for or what does queer mean. These questions are easily entered into Google with hundreds of resources for people to look into.
