If you're going to start a moral support thread for every neckbeard you run into online, you're going to be busy. What are you hoping to accomplish with this thread?

There are literally millions of people just like him, though, and if the rest of the world had to huddle together and sing Kumbaya every time one of them posted something idiotic, the world would grind to a standstill.
It's just some asshole, completely and utterly irrelevant to anything related to you and your life. Spend your energy on something worthwhile instead of crying about what some zero-year-old mouth-breather wrote in an attempt to rile you up.
