I don't know how many of you are familiar with DemoRanch or VetRanch, or anything else Matt has done, but he's a fantastic YouTuber and both of those channels (and the family vlog) are excellent.
His series on renovating an abandon mansion was amazing, and they're still working their way through reviving what was an abandoned resort. Highly worth checking out if you haven't.
I had heard that the shooter was wearing a Demo Ranch shirt, and while that channel is about firearms, it is the least angry or political channel you could imagine. It's just pure fun.
VetRanch is maybe even cooler, although Matt doesn't make as many direct appearances on it anymore.
It's centered around (his dad's) animal hospital where they are constantly saving dogs, cats, and whatever else comes through. It's also super informative, because they'll actually show surgeries and explain how various procedures work.
Echoing Matt from his video above, it just sucks that he got associated with this kind of evil. He doesn't deserve it.
