I'm sure there is some validity to your point.
The support for Palestine and Hamas rally's I have seen throughout the western world since this kicked off leads to believe that the critical mass has been breached and we have probably brought in too many people who do not align with our position in the world, and I would call into question their loyalty to Canada.
How many bad apples spoils a bunch ?
I think we are past critical mass.
To me the problem is home grown terrorism. We ran into numerous issues when ISIS was rampaging through Syria and Iraq where Canadians were quick to trumpet their cause. I think the issue here with Hamas is 10 fold now.
We have western educated multi generational citizens, many of whom have no obvious ties to any extremism quick to support Hamas and the killing of Jews, and we are also seeing some kickback of people who are also no obvious ties to any extremism lashing out at peaceful Muslims.
I seen an article from the US the other day of a White landlord brutally killing their tenants 6 year old child, the only reason was because he was Muslim.
This is the type of polarization that can split a country apart, even lead to civil unrest even civil war, if left to run rampant. This goes far beyond liberal vs conservative, left vs right.
I'm not saying we are at the verge of civil war, but we are already at civil unrest. The events between Hamas and Israel never caused the unrest, it just exposed it. I truly do believe if this stuff is left to grow and become more extreme, that Civil War is a distinct possibility.
I personally think anybody advocating for any violence against civilians anywhere in the world should be charged with terrorism, any non citizens should be deported, any citizens should be charged to the fullest and prosecuted to the maximum.
Ignoring the possibility of civil war, the possibility of this evolving past a regional conflict to something on a much larger scale is very possible.
The elephant in the room, or worst kept secret, is this is all by design of Iran. They have since the 70's wanted to destabilization of the west. Palestine is their puppet, along with Yemen and other places. Seeing the protests in support of Hamas happening here has to bring a smile to their faces.
