My best guess is this:
Creepy men have been inappropriate with the (very young) female audience members at TLDP shows in the past few weeks.
TLDP/ management have had a word with security - saying to keep an eye on men, particularly if they're older and on their own. Maybe to even question men who look shady about whether they like the band, to name records etc.
Overzealous and undertrained staff have taken this way too far and grouped together a bunch of men on their own and dealt with it in the least appropriate, least subtle way they could.
Unbelievable atmosphere. Genuinely unmatched in terms of stadium gigs for me.
Watching the Kop singing You'll Never Walk Alone as Keith Richards came out and started Gimme Shelter is one of the all time highlights of my gigging life
It wouldn't be ridiculous to their target audience though, that sort of language is completely common for a lot of people. And that's ultimately where their money will come from in the future
