You aren't understanding this. The whole concept of branding people as "liberals" is a nonstarter, it's bigotry. And if one uses the example of Canada, where he lives, it's not even a common aspect of discussions between people and how they relate to each other. This whole derisive "liberal vs conservative" nonsense is a largely American thing that has gotten out of control.
Put it this way, if I were to think back to everyone I have ever met in schools, work places, sport clubs, I don't ever remember meeting someone who was so "liberal" in nature that it defined them as a person. And you'd need that to be "despicable" and generate hate for Achilles28. Not that he needs that, he invents a lot of that in his head, and starts randomly spitting on mythical random people that somehow are ruining his world for him. The one he chose in ... Canada !!!
But you know what, all these threads do is help highlight how much conflict there is in the US these days. My opinion, it's harming middle class America but it's your country, you get the country you designed for better or worse. Most Canadians wouldn't want to live anywhere else, and we're ok with many Americans having a distorted or uninformed opinion about us. In fact, it's largely expected, we often make light of it. If US citizens feel the same way, why all the acrimony and pent up hatred on here ? Something seems off.
