apparently, the usual suspects are getting a bit unpopular on social media in the UK:

Social media users who spread racial hatred should be banned from sites such as Twitter and Facebook, MPs say.
The All-Party Parliamentary Inquiry into anti-Semitism wants prosecutors to examine whether prevention orders like those used to restrict sex offenders' internet access could be used.
The cross-party group also highlighted the use of anti-Semitic terms online.
Last week, a Community Security Trust report said UK anti-Semitic incidents more than doubled to 1,168 in 2014.
The trust - which monitors anti-Semitism in Britain - says this was its highest figure recorded since it began work in 1984.

The reason it is pervasive on social media is because the same online media links that report such racist remarks are the same that have links to all the social media on their web pages.
The racists with agendas know this that's why they post the hate, hoping some brain dead reads it and uses social media to spread it. What is amazing the message is seldom nothing more than opinion of the racist scumbags.
