Lol. You're anything but a self absorbed hypocrite, but I also don't have a problem with pettiness. That being said...
What specifically bothers me about his video response is the way he repeats how she's "stalking" him and how she's posting it to her "millions" of subscribers. In a video that is less than 3 minutes in run time, even one repeat is excessive and doubly so in the absence of any other information about how he's coping with it or what real-world consequences he's facing - I believe he brings up the same sequence at least four times. That leads me to believe this could be an attempt to "program" his audience, similarly to how Trump programs his fans through a process of repeating trigger words.
It's neither here nor there for me. While I could care less about what happens to some chick who's willingly engaging in internet drama, I don't like the dude either. However, anytime anyone uses trigger word programming, there should be a pause: this is less about morality or ethics and more about potentially psychopathic traits. At the very least, he isn't a trustworthy narrator.
