Why is Brazil always mentioned for death threats? Where did "come to brazil" originate and why is it widely known? Where there is smoke, there is fire and Brazillian fans have been notorious for doing such things for it to come into the spotlight over the years. You can call him xenophobic as it is normalised and not taken offence to nowadays but racism is the wrong choice of word as he did not get death threats from other ethnic/racial groups except Brazil hence he cannot selectively discriminate and and be 'racist'.
If you are uneducated about the meaning of racism then here it is: prejudice, discrimination, or antagonism by an individual, community, or institution against a person or people on the basis of their membership of a particular racial or ethnic group.
Complete waste of 2 to type this up but lets stay woke.
