Brexit changed people's perception of immigrants for the better

> On the one hand, some voters who supported leave reduced their anti-immigrant attitudes because they felt a greater sense of control after the referendum.

> On the other hand, many people sought to distance themselves from widespread accusations of xenophobia and racism, and consequently became less anti-immigrant in the process.

Most people aren't 'anti-immigrant'. They are anti illegal immigrant. This distinction has been intentionally conflated by the press and political opponents.
