I finally had the chance to watch more of his videos. Although his delivery is a little unorthodox, I think his biggest mistake was/is being so vocal about certain subjects in such a public forum. So many choose to march in lockstep with the "normal" crowd for fear of something like this happening to them, when we see someone being so vocal about such topics (especially when they're not the most articulate), they appear a little on the crazy side.
Sadly, as firearms owners, we cannot be open and honest, or even joke about suffering from any sort of mental illness. So many of our servicemen and servicewomen have been struggling with this for a very long time. Even if they know they are in need of help, many are afraid to seek assistance because of the likely consequences. Stories like this only reaffirm such a thought process.
