I dont see that as a problem, might even be progressively good and forward thinking in modern secular awareness and acceptance of gender neutrality.
The problem is, many of today's self-proclaimed "Liberals" are neither liberal or progressive, in fact, they are bordering on the realm of anti-science most the time and pushing the needle of authoritarianism further and further. If you can't stand back and see that happening, you are listening to the wrong conversations and news.
And it's being pushed by a large force (of whatever you want to call it). I, and everyone I know, and even some people who are considered controversial on the subject of gender pronouns, would give someone the courtesy of calling them by their preferred pronoun. But that isn't enough, you get this type of Trudeau nonsense, and you get people who could face legal charges and being labeled as hate for misgendering someone, either intentionally or unintentionally.
And the problem continues down this authoritarian path, namely the obstruction of truly free speech, curbing fact and scientific discussion in favor of emotive outrage, trying to make laws around something that is nebulous and "fluid". There are heavy implications here. There is much larger discussion intellectuals are willing to have, and it's getting most of them labeled as bigots, even though they are by all accounts truly politically liberal and progressive.
This PC utopian movement should be far more frightening to all of you. You are spending all your time on hating Trump and his bombastic wrecking ball nature, and not giving an ear to what the hell happened to create President Trump and finding a rational way of fixing it. Trump isn't the one anyone wanted break up what is going on, but he is the person (for good or bad) that has shaken it up to reveal some pretty ugly truths about where we are heading. So instead of curling up in this cult-like bubble of authoritarian leftism, start taking a real look at what is happening. Find out what your core values are and who you might share common ground with that you are shunning because of your blind hate for the Trumpanator.
The Democrats in this country could so easily beat Trump if they wanted to, but instead, they are radically doubling down on the same bullshit, even more, rabidly than before, that gave us this anomaly. Real liberals and real progressives need to stop being ostracized and shunned by the authoritarian left for calling out crap like this Trudeau thing because the right is accepting them with open arms even though many of their political ideas are not "conservative". Journalism has turned into political activism (right and left, but left owns most the media), celebrities are posturing as intellectuals and our moral compass... give me a break, I hope the era of these Trudeau hypocrites are almost passed us.
