no dude
stancil is the kind of true believer who has committed his whole identity to the cause.
being slighted by some local antifa goons is nothing to him, he'll bitch and moan a bit but at the end of the day he'll conclude that it's just a few bad actors who mistreated him because they weren't well informed about the situation and also paranoid about secret trumpwaffen agents infiltrating their operations, which is of course justified and understandable to will, so he'll excuse their behavior and continue as usual.
keep in mind this dude literally got a degree in nigger studies. his entire life is committed to being a libshit, it's what he does all day every day, it's what defines him. a guy like that will never ever turn no matter what happens. antifa goons could beat him within an inch of his life and burn his house down and he would still come up with excuses and justifications and reasons for why he should still remain loyal to the cause.
