The thing about the internet is anyone—literally anyone—can use it to express their opinions. There's no vetting process. There's no paperwork required. No preparatory education. All of these unfounded opinions are just spewed out there into the universe. And sometimes the very worst opinions are the ones that get the most attention, i.e. when racists criticized the black Little Mermaid or when men explain to women how periods work.
A recent example of a bad opinion going viral is brought to us by a guy named Hunter Drew who labels himself as a "patriarch." Reading his bio and just a few of his tweets lets you know right away this is a guy whose opinions should be taken with about a million grains of salt. Nonetheless, his recent tweet about ten things women should do to "be a better mother" got under the collective internet's skin.
