kenney has problems with the gays, but his racism is actually quite subtle, as he fully realizes that the kind of socially conservative immigrant that he wants comes from the religious societies in asia and africa, and not the liberal countries of europe or south america. he may be unlikely to accept a coalition with non-white leadership, but he's more open to the ideas that immigrants bring in with them, because they're not very different from his own ideas. so, kenney sees the immigrant as an ally in his quest for a more conservative world, even if he wishes to retain power for himself and his own kind - it's racism lite, a subtler way to be white.
trudeau's racism is more visceral, which is ever the more obvious given that he fucks up every once and again with outbursts of disdain and superiority. there's a list of pretty brutal comments, at this point. the jig is up, really. so, he hides his hate in these choreographed displays of "diversity", using clinical language out of a marketing class. his white supremacy is more absolute, in that he's happy to parade as many different-looking people around him as he can find, but he doesn't have the slightest interest in listening to a word that they actually say, or offering up any kind of position of real authority. how about the bizarre reaction to the raybould resignation/firing, which really had nothing to do with race: diversity only works when it is rooted in trust. what the actual fuck does that even mean? it may appear as incomprehensible word salad on first glance, but it really reveals a fundamentally racist world view: she really was just a token indian in cabinet. so, trudeau sees the immigrant as a voter to control at a distance within a class hierarchy with a white, liberal elite at the top. it's racism with a smile, and you just don't talk about it, because it's not polite.
while the reality is that trudeau is probably defaulting to this because he wants to create a wedge issue with minority voters and can't figure anything else out, that by vilifying kenney as a racist he's essentially acknowledging that he can't compete with him on ideas with immigrant voters and is stuck trying to scare people instead, what you're going to get out of trudeau on this is a lot of projection. most of what trudeau is going to throw out there about his opponents is going to be more true of himself than of them, and it's exactly the reason he's going to throw it out there.
and, a part of the reason that the tories tend to win the immigrant vote in canada is because immigrants can see through this clearly enough. the conservatives are actually willing to accept them for who they are and reflect their actual values; the liberals just pander to them for votes with fake appeals to togetherness, while then passing laws that they stringently oppose.
the liberals are at a dead-end with this. they've tried to build a party around cultural inclusion, only to find out that majorities in all of these different cultures would rather live in a christian society than a secular one, and that the path to multiculturalism is through the destruction of liberalism, rather than the elevation of it. in the mean time, they've alienated swaths of white voters, who are actually liberal and secular in their beliefs.
but, trudeau doesn't live in reality, he lives in a bubble that is curated by his advisors. and, he could very well spend the next six months tilting at these aforementioned windmills, slaying the monster that is the projection of his own inner, racist demons.
