If you like your government, you don’t want anyone to organize against it. And if many people think like you, a truly democratic government would act according to your desires and jail the agitators.
Or, put otherwise, if you use the democratic mechanisms in place, it’s all good. If you protest or demonstrate because you feel you aren’t heard by the government, that’ll usually have an effect. But if, deep inside, you want to overthrow the government, everyone will hate you and you’ll be jailed or worse.
According to communist theory, our current liberal governments are not democratic, because capital exerts control over them by various means. Thus, overthrowing them is necessary. Of course, if we had a democratic government, we wouldn’t wish to overthrow it.
If I’m not mistaken, there were extremely small-scale protests about COVID-19 measures and the government immediately listened and removed them.
