Most Helpful Guy
You have every right to create your own criteria in your mind to screen people; that may be for whatever reason. Majority of people will start having convulsions "oooohh ! You judge people by looks and physical traits"... Don't worry. That's the way everybody is being brought up as a kid. But the reality is, everybody judges another person. It is a natural reaction.
Having said that, I will add, you may create first impressions; but always give the person another chance if YOU get the opportunity.
Now, the things that you mentioned, do you do the same in personal contact with people?
