What you mischaracterize as "racist generalizations" are simply objective descriptions of what a lot of people in Canada (of many different origins and appearances) are currently experiencing and witnessing for themselves each and every day, especially in the major cities, but now also in the smaller cities and even the towns.
Some of the people I've heard from who are most opposed to what's happening are actually Indians who immigrated decades ago, and especially the Canada-born-and-raised descendants of Indians who immigrated in the past.
The first group find themselves once again starting to experience the sort of environment and problems that they intentionally wanted to leave behind.
The second group, especially those in their 20s and 30s, find that their reputations are being tarnished thanks to the negative impacts that unrelated foreigners who happen to have similar appearances and similar names are imposing on Canadian society as a whole.
Also, keep in mind that your false accusations of "racism" and "bigotry" are exactly why so many people in Canada are hesitant to discuss this matter openly and honestly, and why the "data" you claim to want probably don't (and effectively can't) exist.
While some of us are thicker-skinned and have come to expect false allegations like yours, many others just completely avoid the situation by remaining silent and hiding what they're actually thinking, or by giving a "safe" answer that they don't believe. Such people only share their experiences and true thoughts with individuals they've come to trust won't harass them merely for being honest.
