Arguments against heightism discussions

I've heard the arguments against our cause. "Heightism is real, but trivial." "Spare me the liberal victim mentality." "This is nothing that a little confidence and a positive attitude can't cure." "This is all in your head." Blah, Blah, Blah....

We at NOSSA are preparing to put these beliefs to a test. Is this really a trivial matter? Can heightism be eradicated with a change of attitude? Is this really all in our heads?
