Absolutely, which is why as democracy-loving citizens (which honestly everyone should be), people should strongly protest anything that damages it - in a democratic way, as long as that’s possible. And I don’t think Slovakia has regressed so badly yet that there are no democratic avenues of resistance anymore.
It has absolutely not, and it goes without saying (but is nevertheless worth repeating) that this is completely unacceptable. As long as you’re free to demonstrate without risking your safety and the outcomes of elections matter, leaders should be chosen at the ballot.
It’s an interesting question how bad the state of democracy needs to be before one is justified to stop playing by the rules. There is a breaking point somewhere, and politicians killing off scrutinizing journalists are clearly moving towards it in a dangerous way. But it is nevertheless clear that Slovakia remained far away from the breaking point of anything like this becoming necessary.
