On the 100th anniversary of Polish independence, some East Vancouver parishioners were shocked to find their Polish Catholic church defaced with graffiti.

St. Casimir's at Inverness and East 27th Avenue was covered with the word "AntiFa" in huge letters, as well as anti-Nazi messages and a symbol of Poland's far-right party.

AntiFa is a violent left-wing group that has clashed with fascists in the United States. It was recently in the news when some of its adherents gathered outside the home of Fox News host Tucker Carlson.

Poland is ruled by a right-wing government. Its right-wing president, Andrzej Duda, participated in a march in Warsaw this weekend that was organized by far right-wing forces, according to the Guardian.
