Say the magic words, everybody: “diversity of tactics” 
It occurs to me that some folks may not know what I mean by "diversity of tactics;" briefly it is the phrase used by Hard Lefties to describe the way that they deal with the fact that different people and groups have different opinions, methods, and willingness to do things.
For example:
-- fervent young anarchists want to break shit and set things on fire
-- disruptive protestors want to shock the system and feel powerful but don't want to do serious criminal shit
-- normies want to go out and do a nice march and feel connected to the community
-- fervent young anarchists want to break shit and set things on fire
-- disruptive protestors want to shock the system and feel powerful but don't want to do serious criminal shit
-- normies want to go out and do a nice march and feel connected to the community
So how do Lefties make space for all these kinds of people? Diversity of tactics. Agree that people will do different things. Keep it separate, by space or time. Don't interfere with or snitch on people who use different tactics, and they won't call you a bad person or a sellout.
Note that this requires an a broad militant community that doesn't have its head up its ass whose members are willing and able to conduct negotiations with each other and obey norms about who is in charge of what action takes place at a given space/time.
