Ideally, the rule of law decides.

Unfortunately it very often is susceptible to political and economic influences. And the courts are not in the streets, where the attacks happen. Far too often the police turn a blind eye to right wing incitement and violence (due to a large number of sympathizers in the police), so sometimes direct action is the only way to show fascists and other hatemongers the error of their ways.

"sometimes direct action is the only way to show fascists and other hatemongers the error of their ways"

Unfortunately, the actual history shows that doesn't show them the error, but is more likely to increase the resentment and resistance.

[KozmoNau7]

Unfortunately, direct and sometimes violent action is the only language fascists seem to understand.

And again, are we to assume that it is you who will decide who is a fascist and who is not?

And why such a discrimination of communists, who are far more deadly and dangerous than any "fascist" (your Soviet terminology is showing; surely you mean nazis of different stripes, not comparatively vegetarian Italians).

Despite what my username may imply, I'm not Russian nor a supporter of the USSR.

Fascists are a very real problem today. Communists are not.

[Fins]

It is generally a Soviet trait to conflate followers of Mussolini with nazis.

Arguably, communists are a greater problem than fringe nazi groups exactly because while being a nazi is not acceptable in a decent company, being a communist unfortunately is despite all historical evidence of their dangerousness.

But you are still avoiding the key question -- are you taking it upon yourself to determine who is a "fascist" to suffer consequences, and who is not?
