Public spaces, conflict, and refraining from hating enemies

s I see it, if I support freedom (true liberation, not the fraudulent  ‘freedom’ to oppress others or to enjoy one’s privileges that others are deprived of) I’ll appeal to a common understanding of reality. 
For that to be useful in building grass roots power, it must take place in the public square so to speak, and include those with whom we have mentally painful disagreements. 
Social and other media is useful in that it enables us to engage one another beyond the constraints of time and place.  But its downside is that if it we neglect contestation in public, in-person real-time spaces, we engender a type of political tribalism that feeds fascism and other abuses of power. 
One of the useful points MLK stressed is that freedom and other positive goals are impossible to achieve without conflict, though of course he emphasized strategically nonviolent conflict. 
Violence will come sure enough no matter how much we strive for love and kindness as social movements,  because those in power will use violence (via police,  military,  vigilantes, plus the economic violence of blacklisting…etc) in an attempt to continue their abuse of power. 
But for me, strategic nonviolence seems the best path for the social movements I care about. 
That strategy requires a ‘spiritual’ though not necessarily religious dedication to our commonground as inhabitants of earth. That involves striving for a very difficult and uncommon type of love toward enemies, because hatred addles the mind.
This sort of love Christians such as MLK referred to as agape. In my experience so far, this sort of love seems similar to what I imagine parental love would be like, whereby instead of giving in to our hatred we are sad and disappointed when we see moral repugnance in fellow human beings. 
Instead of being intoxicated with hatred, it makes sense to be sober when we see moral repugnance in others, sober in our awareness that potential for such moral ugliness lurks within our own psyches at least latently, given our shared humanity with both those who embody the worst and those who embody what’s morally best in our species
