Are you sure they are? Probably most people in your country would label you as far right for championing free speech, no other issues considered. Probably you are doing the same for others.
Yeah. On pretty much every other topic important to me, their official positions are either diametrically opposed or lean into another direction far enough that supporting other parties would be a better choice.
Every faction claims they support free speech and every faction also supports suppression of certain types of speech.
