UK comparison: https://www.bbc.co.uk/news/uk-england-london-47996907 ; black woman MP has a train can, everyone treats it as a massive scandal. I think someone had a survey once where they found that one third of all hate mail and death threats directed at UK MPs was aimed at her.
*In theory* the problem wasn't the drink, but that it was on the train. Even in the UK, Farage is famous for drink-related photo-ops.
I'm emphasising "in theory" because it took a lot of concerted pressure for Johnson to leave after actual pictures of him celebrating with alcohol during the pandemic, so of course it was more an excuse than an actual cause of the vitriol against Diane Abbott: https://en.wikipedia.org/wiki/Partygate
