No, it is recognizing that unlike most democratic reactionary groups most fash have a explicitly physical agenda that needs to be countered physically as well.
Like their great examples (hitler, mussolini, Franco) fash believe that the road to political power starts by conquering the streets, what in Germany they call "national befreite zone", and since this always involves cleaning the neighbourhood of the homeless, the immigrants, the queers and those troublesome leftists the police and reactionary politicians look the other way.
We, the workingclass, need therefore to be willing to defend ourselves physically against these physical attacks.
Now often the best defense is the offence, this in general doenst mean bashing every idiot fash his brains in but it does involve targeting, if you want terrorizing, the leadership and their infrastructure, force the leaders to give up, drop out, find a job and start a family and at the same time make every meeting, demonstration, concert, etc a failure. shatter their image of hard as nails untouchable top boys as that's their main recruiting tool. most fash drop out of organised street activism first and only later and only later start to reconsider their bigotry when they are not anymore drenched in propagada 24/7.
Also don't believe the "isolated fash are more dangerous" myth the liberals love to push, the so called lone wolf does not exist, 99.9 percent of the time "lone wolfs" are either part of organised fash groups or they desperately want to impress one.
The mind is its own place, and in itself Can make a Heaven of Hell, a Hell of Heaven. What matter where, if I be still the same, And what I should be, all but less than he Whom thunder hath made greater?
Here at least We shall be free
