Unfortunately, what most people on this forum fail to realize is that the point of contention of this bill has never been the 3/5 rule or pre-PR credit.
Conservatives have done a pretty good job of painting this as a bill that gives citizenship to terrorists and for the most part the Liberals are not even fighting it, in-fact they can be quoted on multiple occasions, defending why dual-citizen terrorists should not loose their citizenship. I personally think a better defense was: all terrorists should loose their citizenship, since this cannot be implemented on certain citizens at the moment (UN resolution on statelessness), we cannot single out Dual Nationals. But I am not a Liberal MP yet.
Returning to the point: Due to the perception created by the Conservatives, there are a large number of citizens calling their MPs (Con, Lib, NDP) to oppose this bill (not my opinion, I know it to be true). This is the reason Liberals are being extra careful with this one point of a bill that has many other sub-sections.
As a social experiment, you can ask some of your dual-citizen friends who have been living in Canada over 10 years and ask them about the bill that effected dual-nationals (they probably won't know what C-24 is). I can bet you that majority of them think Trudeau already passed that bill ages ago, since it was part of his campaign promise and bill C-6 (for those who have heard about it) is only about the 3/5 rule.
If we (the members of this forum) collectively, had spent more time educating existing dual-citizens about the importance of this bill for their future, instead of arguing whether this bill was going to pass ASAP or it was DOA as soon at it reached HOC, we would have even had the support of registered Conservative voters that are Dual-Citizens.
Anyway, sorry for the rant, I have condensed several conversations I have had with Conservatives into this little post, so hope it does not loose its intent.
