I'm sure that these people donating hundreds, thousands, or even tens of thousands of dollars to streamers are all poor people living in studio apartments. /s
You know, some people have lives, whether it be involving jobs, careers, education, relationships, etc. Watching streams is a good way for them to enjoy their passion of gaming while not having to commit the time. They don't all have time to level an Enchanter to 60 on EverQuest in 2016 and make 10000 posts on an elf simulator forum like you.
It's funny that you're trying to argue that people that watch streams are only neckbeards. I'd argue that the neckbeards are actually gaming, like yourself.
