Sorry, but how can you say that the brexit empowered racism in GB? The rise of hate and acts of racism shortly after the brexit is no evidence on the long term. Furthermore, racism existed before the brexit as well. The same is in the US, racism exists, no matter what party the president elected belonged to. Giving Trump the “credit” for making things worse is way to simple. The emotions during elections aren’t equivalent to emotions after the election. We will see in summer 2017 how the president (who ever it may be) and his governing has chance the US, or how the public opinion has changed the governing of the president.
Until that, stay calm and keep on blogging.
