People like thinking the best of themselves, which is partially why we have "trigger warnings," "microaggressions" and claims of "taking offense" -- so these complainers don't have to come to terms with the fact they're spoiled, self-absorbed, tyrannical brats.
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.
