If you are some sub-majority of the population, and you go after groups you don't like unilaterally by illegally taking action against them, that doesn't seem democratic at all, really.
It could be fair to say they deserve it, I don't know enough about French politics. But I don't see how that particular type of action could be described as democratic. Lots of groups claim they are the good guy and/or represent the will of the majority, but I think it would only be democratic to substantiate that and take action through elections.
This could describe any of a litany of actions taken by pretty many so-called democratic governments, who represent an even smaller number of the population than the unions in question.
The problem is that we have destroyed the meaning in the word "democratic"
