Do you feel people (especially on the internet) have an inflated sense of entitlement

That is a terrible example. Everyone has the right to train in peace.

I'd like for someone who disagrees to actually post here, but I don't think they will because there's no justification or good rationalization for how selfish most people are these days.

It's ironic if you think about. People who claim to be entitled to one area VS someone who claims to be entitled to the whole world... in a manner of speaking.
