Oh just some loser ranting about how he had 3 college degrees and followed all the "rules" of civilized society and was basically an unemployed virgin living in his parent's basement in his 30s. He was pissed how he wasted his life doing the right thing, though he wasn't screaming too much about it, it was more of a calm anger.
The "inspiring" bit was my of saying "Hey look at this video and be happy you aren't this guy!"
In any case, I'd imagine the virgin bit was the worst of it. I mean that's what he seemed the most upset about, but that factor is more on him. Seriously, I've known tons of lowlife unemployed assholes still living at home that were still managing to get laid.
If the video has been taken down, I'd say he might have cracked and gone on a shooting spree, however he was in the UK not the US so he probably just committed suicide instead.
