I agree somewhat, I didn't notice as much bad language when I had a season ticket, compared to recently. Other than odd drunken idiot, most fans swore at valid things. But I still don't agree with yellow cards. In think now people increasingly live insular lives, they don't know their neighbours, they don't go to local pub. So when they hear views or language they don't like, it's considered extreme, whereas in past, you knew that gobby people would eventually meet wrong person and get their face smashed in, so you ignored them. I'd guess you know have more middle class professionals, sitting near people who aren't as articulate and they can't handle it. So snitch to club, when somebody shouts at Jack Grealish.
