So I guess we have to agree to disagree on this. In my adult life I went to in excess of 3,000 gigs and that's not counting the ones I went to as a teenager. And that's just the shows I went to. That's not the number of bands I saw since every gig had at least two, and often three, bands on the bill. The vast majority of bands that I saw, I didn't see significant levels of discomfort in engaging with the audience. Maybe now and again with a band right at the start of their career but, otherwise, no.
But it doesn't matter. We've had different experiences, we have a different view on this.
