You have been a victim of weaponized disinformation.

Justin was just the face of a craven centrist party who leans whatever way the public will vote them in for. He just was a popular and somewhat irreverent and surprising figure and he caught fire with voters, and then when the Liberals did the same shit they always did but just with his sunny presence stamped on it, the disinformation trolls led you to believe he was the person responsible for all of that. When he's only a part of it really, and a massive engine drives everything the party does, funded by deep pocketed people who control everything in truth, and also on the other side pay the people who feed you disinformation from the conservatives with their cringe little commercials and big talk every time Trudeau and the party misstepped. A lot of people held their nose and voted for him because they don't want the conservatives, and I'll hold my nose and do it for Carney too, but I'm sick to death of old white men.

I really recommend you learn what disinformation is before you decide on any other beliefs. Here is a primer. https://www.cna.org/reports/2021/10/psychology-of-disinformation-key-psychological-mechanisms
