She's not being dismissive, she's pointing out the cost to them has been extremely high. It is easy for us to say what we'd do in their place, or if we were in Russia. But taking a principled stand is hard, and the cost to doing so can be beyond what most people can bear.Yes, we don't know what will happen in the next few weeks, or months, or years. We don't know how events will play out or how the war will impact the course of politics in Belarus, or Russia, or much of Eastern Europe. This is the largest war in Europe in more than two decades, and it's likely to get much larger before it ends. We may not know the impact of these events for decades to come, and just because @TAHbKA wishes to be dismissive of the efforts, and sacrifices of people who are fighting for the freedom doesn't mean that I have to be.
As for the athletes who took part in the pro-war show, either they wanted to be there, which is awful, or they didn't and were pressured because authorities have some hold on them. Which is awful in a different way.
Obviously these challenges are not equivalent to those being experienced by people in Ukraine. There are also people in the world who have had it even worse than the population of Ukraine. It is possible to have compassion for those experiencing different types of adversity, even if some are more extreme than others.
