Blame-shifting In Heightism

Quoted from here:

Always look at heightism as a problem from the perspective of the people who practice and perpetuate the prejudice. Not from the perspective of the people who are negatively affected by it. 

In other words, think "why did John say that Steve wasn't even 5'6" 'on a good day' - does he mean that 5'6" is better than 5'4"'? 

Do not think "why did Steve get offended when John said that he wasn't 5'6" 'on a good day'? Is Steve sensitive about his height?"
