It's about the right length (c8%); gives a little relevant background and context, indicating that the writer has thought about what a stereotype is in its broadest interpretation; makes some initial references to sources; and finally focuses precisely on the question, showing the reader that it has been fully understood and that it will be answered. Note that the wording of the final part of the introduction is very close to that of the question. If the essay follows in the same vein, it should get an excellent mark.

That’s why sometimes students can be afraid to share ideas, because before they were stereotyped as nerds. These days’ people are afraid to be themselves, because they fear other people. They don’t want people to think something bad for them. Secrets, thoughts, and ideas, are all held down. Stereotypes can be an obstacle as to how open you are with people and how you make people feel when you are with them!

Both groups now are under siege, Mexicans and other undocumented immigrants fearing deportation daily, and Muslims increasingly being attacked and even killed for their relgious beliefs.
