Dianne Abbott has undoubtedly been trolled and suffered awful racist abuse, received the vilest of threats from social media.
Other MP's both female and male have also suffered the same.
Try walking in the shoes of most MP's such as Jacob Rees Mogg, Boris Johnson, John Mann, Margaret Hodge, Lucianna Burger, Ruth Smeeth, Priti Patel, Sajid Javid, Tim Farron etc. etc. etc.
Perversely there are posters who have been extremely nasty occasionally about MP's they dislike, verging on hate but who do not see themselves as perpetrators whilst chastising others.
Couldn't make it up.
