Provide a better alternative if you can. In reality it is hard, very hard. The USSR was discontinued because people wanted freedom but it destroyed the economy and created widespread unemployment and poverty. Next to Belarus is my country, Latvia, and people are leaving it in droves to better European countries even though Latvians have democracy. It has failed to ensure economic prosperity and the freedom alone is not enough.
It is easy for those who live in rich western countries that were developed with hard work of your forefathers and often with great social injustices like slavery or working conditions that were close to slavery. Belarus may have less political freedom but the life there isn't slavery.
While the Belarus people should demand more freedom, they should learn more diplomatic ways to achieve it. First, they should understand how politics work and why their current protests are just a waste of time.
