What he's saying is that he doesn't think this motion, and the study which follow, will necessarily recommend limits on freedom of speech and expression similar to those put in place by progressive governments in parts of Europe. That is neither rational nor irrational, and it certainly isn't factual. It is merely his opinion. But given progressives' well-known lack of commitment to freedom of speech and expression when it causes offense to minority groups, and Trudeau's dedicated, even zealous support and defense of Islam, it's a reasonable suspicion that the conservatives are correct.
