Here’s how it works: when accusing you of “microaggressing,” the truth is that, generally, these snowflakes just don’t happen to like what you’re saying. But shouting “Shut up! I hate that type of expression!” makes you seem intolerant. So to preserve your image and self-image, you use the ploy of shifting the onus onto the one whose speech you want to suppress.

So...when the author says you, does he really mean you or does he mean me, or who exactly does he mean?

Everyone is you. No He, they ,she, them... the closest is these.

The author uses “you” to mean anyone singled out by these PC tyrants, which includes nearly anyone with a conservative thought in their heads.
