I think the plug should have been pulled on the Glasto thread ( or rather the Oh Jeremy Corbyn as it was called) but not because anybody disparaged Corbyn (every right to do that) but all the personal snide and childish comments that were directed at posters.
If posters limit themselves to talking about politicians of all kinds and not each other, it would be a good thing.
To answer the OP, I think music events, even Glastonbury, would be a lot better just concentrating on the music.What we had was Corbyn saying he will be PM in six months and McDonnell, inciting the crowd ( or trying to, weak applause) by saying that residents of the fire had been murdered.
