OK, I may have some issues with other European countries but conscription is definitely a greater violation of individual rights than hate speech laws. Forcing someone into a position where they could potentially die in an entirely unjust war does not uphold freedom.
Also, being in the military and fighting for freedom are not the same thing. The military mentality, at least in the US, is one of unquestioning or nearly unquestioning obedience. That is hardly beneficial for democracy.
I actually don't have any particular opinion on Switzerland though. I am not very familiar with that country.

Could you please elaborate on why you think conscription is a greater violation of individual liberty than "anti-hate speech" laws? All conscription does is ask that citizens perform their civic duty. How is it any different from, say, jury duty?
If you live in a democratic system, even a military-esque democratic system, then the decision to go to war was made with the approval of the people [or at least their democratically elected representatives]. If you don't agree with the war, then you have every right to vote against it, protest against it and help convince others to oppose the war. Those are your rights in a free and open society.
Conscription is a greater violation of individual liberty than hate speech laws because it puts people in a position where they could kill or be killed by others without giving them any say in the matter. It is one of the most authoritarian government institutions you could possibly have in a society that still has a democratic political system.
Unfortunately, fear-mongering, human aggression, and bad logic ensure that there is always going to be some chance of getting the voters to support a stupid war. If everyone is forced to fight it, regardless of their personal views, than you have a tyranny of the majority. There is no protection of minority rights. To answer one of your questions, it is different from jury duty because of the vastly greater consequences for the participants.
Now, such a system can be neccesary in extreme circumstances. But so can other authoritarian measures. This does not make them desirable in an ordinary situation.
