I don't think that many Lithuanian politicians are particularly uncomfortable with anti-fascist issues per se. But the political culture is such that historical details (say, regarding Jews in WWII) are not widely known or discussed, neo-Nazi threat is not taken urgently on personal level. Higher officials routinely say the right things, and active opposition is demonstrated by some commentators. Probably in aggregate, more discomfort is in the silent "pressure" to allow sympathizers disproportional influence.

The equal treatment of extremists is still in the conditioning phase in Lithuania, to my opinion. More so than, say, in Estonia (which symmetrically banned swastika and hammer/sickle some time ago). The question is, how many parliamentarians fully knew (or cared) what equivocationist model they are following.

If I have time this month, I'll try to prepare a diary. But my view is not very standard; I'll have to check recognizably accepted hierarchies of facts.
