I am searching for a word that qualifies a person as someone who makes sweeping generalizations on almost everything and tends to stereotype people. He picks up one trait of a person (something which is dominant) and every other person with a similar trait becomes just a prototype of it. He fails to elicit difference in the other aspects of their character and in understanding them in a more detailed manner.

This question appears to be off-topic. The users who voted to close gave these specific reasons:
- "Questions on choosing an ideal word or phrase must include information on how it will be used in order to be answered. For help writing a good word or phrase request, see: About single word requests" – Community, tchrist, Brian Hooper
- "Please include the research you've done, or consider if your question suits our English Language Learners site better. Questions that can be answered using commonly-available references are off-topic." – BiscuitBoy, ab2
The obvious answer would be:
- Prejudiced: having an unreasonable dislike of or preference for somebody/something, especially based on their race, religion, sex, etc.
Synonyms: narrow-minded, bigoted, intolerant
- Biased: having a tendency to show favour towards or against one group of people or one opinion for personal reasons; making unfair judgements.
How about a universalizer? Those who universalize typically make sweeping generalizations.
What about generalisor to describe someone who generalises?
Generalizator --> someone who generalizes Terminator --> someone who terminates Generator --> someone who generates
Short sighted or narrow minded would maybe come to mind. More the former than the latter.
