I Have A Low Bullshit Tolerance

I can handle someone harassing me with racism or about my molestation, those are two issues I've conquered and am able to deal with such people with ease. What I can't handle are people talking out of their asses with me! I can't stand it when people do things like trying to tell me I'm wrong about something that they themselves know absolutely nothing about! This is why I don't usually vent about my personal issues here anymore, there is always at least one person trying to give me crap and side against me. I've tried being nice and reasoning with them but I learned the hard way that it's always pointless. They'll argue to the bitter end even when they clearly have no argument. It frustrates me so much and brings out the worst in me! How do these people have the audacity to so stupidly mouth off and act like they know what they're talking about when they don't?! I don't know why this bothers me more than the other aforementioned things that you'd think would really get a rise out of me, maybe even more justifiably so, but I have little tolerance for people who are so narrow-minded and full of themselves.
