Well then what will you accept? If reports from your own government that you supported doesn’t suffice, then what will? Do we have to wait for one of them to be shot? Oh wait……..Let's not throw out stupid analogies here, talking about child abusers and what not.
It should be mentioned that Canada does not consider the vast majority of pro-Khalistan groups to be terrorists (I think there is only one that is). There is nothing wrong about peaceful protests. They weren't throwing bricks or burning flags. So, while you might want to paint them as something untoward, they are not. So, what does it come down too? Religion or skin colour? Or both? Canada is a multicultural place. We get a lot of Asian people here, because surprise, surprise, the largest group of people in the world are....Asian. And you are not doing a great job explaining how they are incompatible to Canada.
I don’t think most of Canada knows what Khalistan is. This has nothing to do with rejecting multiculturalism. That is a lie you created to save face because of your own prejudice.
