Prejudiced people.
(especially those that judge people according to their sex, race, blood type, appearance....)
Those that say you don’t like people with type A and AB blood types.
You probably hang out with Type A or Type AB blood typed English Speakers (Canadians that do not know of their blood type) and suck up to them only because they are white.
A lot of people are prejudiced and I don’t blame them because I am too... but you should get to know them before you say anything.
