Yes, this sounds ridiculous, but is indeed true. We've had a lot of reported incidents here in England. People are imbeciles. I'd assumed that our intellectual wattage had moved above this sort of level hundreds of thousands of years ago. Apparently not.

"On Thursday, police in Belfast appealed for information after a mobile phone mast was damaged in an arson attack, with online footage suggesting the motive was opposition to 5G networks.
The video clip shows an incident on the Antrim Road in north Belfast on Thursday night, in which flames can be seen at the base of a mobile telephone mast.
According to a report in the Irish News, voices can be heard stating “Fuck the 5G” and “Viva la revolution” as the fire burns.
Facebook removed one anti-5G group in which members were being encouraged to supply footage of them destroying mobile phone equipment. Video footage of a 70ft (20m) telephone mast on fire in Birmingham this week has also circulated widely alongside claims it was targeted by anti-5G protesters.
The problem has become so bad that engineers working for Openreach, which provides home broadband services, have posted pleas on anti-5G Facebook groups, asking to be spared from on-street abuse as they are not involved in maintaining mobile networks."

And here's a photo from last week of a burning mobile mast in the UK.
