My understanding is that the PC culture backlash is the intolerance of “snowflakes”, which I’d define as individuals who place the value of opinions over fact, are unable to entertain both sides of an argument at the same time, believe safe spaces and trigger words are more important than freedom of speech, or are unable to tolerate criticism or the expression of ideas drastically different than their own.

This is just scratching the surface without talking about the possible use of diversity and inclusion efforts as sanctioned discrimination.

Your definition consists of one description that distinguishes "snowflakes" (safe spaces, etc), and three general, similar flaws that apply equally well to their counterparts within the "anti-PC" crowd. I think that's probably the (sarcastic) point the parent comment was making.
