Why was there so much violence at gigs in the old days?

A few weeks ago I posted on my Instagram (nemtheanga_primordial) some old ticket stubs from the mid 80s to the early 90s and sure enough the violence that surrounded those shows got mentioned in the comments, so I thought I'd revisit that, the reasons why it was happening, a stabbing at a punk gig in 1977 which cast a shadow over gigs in the State for years and I ask, was it just a British isles and Irish thing? if so, why? How it stopped, why gigs now are often just corporate and empty feeling and whisper it....those were the great days, the classic gigs and we wouldn't have it any other way....My Youtube channelhttps://www.youtube.com/@AlanAverillNemtheangahead over there and subscribePrimordial on Spotifyhttps://open.spotify.com/artist/0BZr6WHaejNA63uhZZZZek?si=yFFV8ypSSDOESUX62_0TzQsponsored by Metal Blade records https://metalblade.indiemerch.com/promo code AA 2024 for 10% off your order ships worldwideFor info on my work as a booking agent go to: https://www.facebook.com/DragonProductionsOfficialI made some very brutal old school death metal right hereVERMINOUS SERPENThttps://open.spotify.com/artist/54Wpl9JD0Zn4rhpBvrN2Oa?si=zOjIulHXS5y9lW1YHMhgTACheck out my other doom bandDREAD SOVEREIGNhttps://open.spotify.com/artist/60HY4pl0nbOrZA6u2QnqDN?si=sxQ5_1htR6G3WIvy1I_wXAand take a listen to some old school electro goth I madeAPRILMENhttps://open.spotify.com/artist/7GzLO1YJClmN5TvV4A37MJ?si=cRXSk24lQKWSqJG-B8KbWQSupport this show http://supporter.acast.com/agitators-anonymous-the-alan-averill-podcast.
