if they really wanted to help, they'd call that girl a fucking retard for being drunk outside alone dressed like a slag so that any guy can easily take advantage of her. most people actually only recognize the stupidity of their actions when that stupidity leads to bad outcomes. this is true for literally everything. think of how many women who overwhelmingly support immigration, suddenly have a wake up call when those immigrants start molesting them on the street in public. or when they suddenly start getting their phone snatched from them in daylight. or when they suddenly find themselves not wanting to walk alone at night. only then do they make the connection that immigration = bad, and that connection was only made through bad experiences.  now in a normal, healthy society, the men already realize this, and take actions preemptively to protect women from themselves and their lack of personal experiences. but women have rejected mens preemptive protection in that regard. and so, women must learn themselves. it fucking sucks, but that's just the way reality is. you keep white knighting for women en mass, and they will never learn anything except that "it's fine, if something goes wrong, random strangers will help".
