constitutes proficiency is often illogical

As a form of prejudice, linguicism is often more subconscious than other forms, possibly because not much attention has been raised about it; it is not a cultural taboo as racism and sexism are today. Furthermore, many feel that it is not logically unjustifiable or morally reprehensible to draw inferences about a person's education partly based on their linguistic proficiency. However, as most linguists note, the definition that such people use of what constitutes proficiency is often illogical.
