Sinn Féin are pro EU.
Sinn Féin are not an Ireland First Party.
Sinn Féin are not an Irish Sovereignty Party.
Sinn Féin are not a Catholic Party.
Sinn Féin are not Nationalist.
Sinn Féin are pro Open Borders.
Sinn Féin are pro Mass Immigration.
Sinn Féin are pro Political Correctness.
Sinn Féin are EU Unionists.
Sinn Féin are dedicated to the creation of a socialist republic.

The only reason Sinn Féin appear nationalist and Catholic is because in the North, the Irish Catholics have traditionally been oppressed, which fits perfectly into a Marxist credo (Marx was very clear that if Nationalism can be used to bring about an international Communist order, then use it, but it has no intrinsic value to socialism). South of the border they have done little to keep Ireland patriotic, sovereign and Irish, and have supported nearly all types of political correctness and the EU.

Many people still vote for Sinn Féin because the think they are nationalist and fighting for a sovereign Ireland. They are not. And this is a lie Sinn Féin keep peddling to voters.
