Some people are very quick to come to the aid of a woman because she is perceived as being , weak, and unable to provide for herself. these same individuals may be quite a bit less likely to come to the assistance of a man in the same situation. though these people may have noble intentions, this is still an example of sexism.

Explanation:

Benevolent sexism is a type of prejudice expressed in terms of apparently positive emotional statements and responses. Despite this kind of prejudice associating things considered good with certain groups, it still results in keeping group members in lower positions in society. Benevolent biases can help to justify any hostile biases a person has in a group.
