LEARN NOT TO GENERALIZE FROM YOUR OWN EXPERIENCE.

That's a general principle for learning how to think.  It's a principle often distorted.  Consider the way in which "Easy for you to say" as a way of suggesting that an individual is taking for granted advantages that others might enjoy has mutated into the somewhat more intellectual-sounding "check your privilege."  That's apparently become a term of art among the Perpetually Aggrieved at the Ivies  -- perhaps there, students do not struggle with "divestiture" or "obviate" -- and a Princeton student suggests that some users of the phrase are themselves profiling others.

Behind every success, large or small, there is a story, and it isn’t always told by sex or skin color. My appearance certainly doesn’t tell the whole story, and to assume that it does and that I should apologize for it is insulting. While I haven’t done everything for myself up to this point in my life, someone sacrificed themselves so that I can lead a better life. But that is a legacy I am proud of.

A Salon columnist responds to that column in a nasty tone that is unlikely to make anyone not predisposed to accept her argument accept her argument.  That despite her making the correct point that not everyone experiences the same obstacles in the same way.  It's a missed opportunity, as any time one of the Perpetually Aggrieved begins an argument with an "As a ..." the logical error of generalizing from a small sample is sure to follow.

I'll give John McGinnis the final word.

If your underlying argument is flawed, you do need a force other than logic and evidence to sustain your position.  Political correctness is an admission of intellectual frailty.

Indeed.
