When it comes to E'R, the reason why he's enjoyable to watch is simply due to the fact he's funny and doesn't care what people think about him.
He's the type of guy you can hang around with while having a laugh.
It's the same reason why everybody loves watching Mister Metokur. He wasn't afraid to point out people's flaws and laugh at their mistakes, nor would he apologize for any of the jokes he made.
When you compare him to other Youtubers like Hiding in Private, a man-child who's so desperate to defend a terrible show, Steven Universe, he will make multiple views to prove how "good" it really was, even getting arguments in the comment sections about gender, an ideology which Jhon Money created.
The man had experimented on two boys to prove that gender could easily be changed at birth but ultimately failed due to both patients killing themselves.
And while Hiding in Private still agrees that he’s a monster, he will still defend John Money's ideas roundaboutly, the same ideology that causes two boys to be mutilated and commit suicide.
He has to because otherwise, he would face the horrible reality that everything he knows is wrong.
He's only defending Steven Universe because he is a very sexually confused and painfully insecure boy.
So, Hiding in Private will go on to continue this sad crusade for a show about Gay Lesbains Space Rocks & their Autistic kid, who’s also his Mom.
It’s a battle that nobody the Most terminally online people suffers severe cases of troll remorse, all because somebody committed the sin of making fun of their favourite show.
The same show they themselves didn’t care about until everybody else made fun of it.
And yes, he's the type of person to get into arguments in his own comment sections constantly.
Just take a look at his "brilliant comebacks."
