“In those areas controlled by Liberal governments unwilling to prevent violence by Antifa, BLM, etc., counter force violence by civilian groups may be the only solution available. “
Counter force by civilians, especially groups, in liberal controlled areas will be met with military type suppression. Such action would, almost by definition, take place against protected minorities and would be deemed “hate.” The only thing the average person can do to protect themselves in a liberal controlled area is leave.
When I say counter force, I don't mean obvious (i.e. uniformed).
In Liberal areas, counter force troops would have to quickly and easily blend back into the crowd.
I have watched some videos of the Proud Boys. They are much too obvious too avoid the kind of problems you are suggesting.
If they (the Proud Boy types) really want to be effective, they need a very low profile or at least take a two pronged approach in which some of their troops are high profile and some are almost invisible.
As an aside, there is no doubt that "high profile" behavior of Proud Boy types of groups is the best way, if not the only way, to recruit.
