so, what do you do when you wake up one day and realize you've got thousands of chinese spies in the country causing instability with the intent to overthrow the government?

well, you figure out if they're here legally or not, first. if they are, then they get freedom of expression, even if they're foreign agents - sorry. it's up to us to figure that out on our own, and ignore them, not up to to the government to track them down and punish them for what our constitution is explicitly in place in order to sanction.

but, it should also be a bit of a wake-up call.

1) there's clearly an issue of infiltration that should be addressed through running more stringent background checks. if the chinese government is going to do this kind of thing in canada, it should expect retaliation in the form of extra precautions to make sure we're not allowing spies in.
2) a good percentage of these people are probably not here legally, and the ones that can be identified should be immediately deported - once they've received their due process.

trudeau should not ignore this, as it will just perpetuate the idea that he's a door mat that the chinese can walk all over at will.

he must retaliate.

and, jagmeet singh must cut his beard, too.
