I am not in favour of taking down any statues at all. Macdonald's treatment of First Nations is well documented and has been widely discussed. I'm beyond annoyed when people still try to claim there are those who don't know, and removing the statue will be a small step towards education and reconciliation.
However, somehow, Wilfred Laurier is rarely if ever brought up. Is it because he's Liberal? I don't know. But I do know that his immigration policies were very racist and discussed openly in parliament. Also, he did nothing to change anything that JAM put into place. Example: JAM legislated a $50 Chinese Head Tax; Laurier raised it to $100, then $500.
Then there's Mackenzie King. He banned Chinese immigration altogether, on July 1, 1923. During the Dirty Thirties, he said he wouldn't give a red cent to anyone who didn't vote Liberal. Then there is the treatment of Japanese Canadians during WWII.
