Alexandre Bissonnette, who was charged late Monday with six counts of first-degree murder and five counts of attempted murder, is a fan of U.S. President Donald Trump, French far right leader Marine Le Pen, the separatist Parti Quebecois and Mathieu Bock-Cóté, a Quebec City columnist known for his pro-nationalist and anti-multicultural views, according to what appears to have been his Facebook account.
...On a Facebook post they said they learned “with sadness and anger about the identity of the terrorist Alexandre Bissonnette, unfortunately known by several activists in Quebec City for his viewpoints that were pro-LePen and anti-feminist, as expressed in social media and at Université Laval.”
...According to La Presse, Bissonnette was often bullied at school.
“In high school, he and his brother didn’t really have friends. Alexandre certainly had an anti-social personality,” said Stéphanie Guimond, who attended the same high school.
Said Marc-André Malenfant, who also attended school with Bissonnette: “When we spoke of him and his twin brother, we called one ‘the mean one’ and the other the ‘gentle one.’ His brother was much friendlier. What I remember most about him is hi arrogance.”
