Absolutely. The stupid posts from people like jfern, iBizBee and GoTfan make me not want to support Sanders and ashamed I do now. But then I read posts from people like James Monroe, Invisible Obama, RFKFan68 and especially of course Landslide Lyndon, and I get SO hyped up about backing Sanders. I'm not kidding when I say literally no person on the Internet has made me more supportive of him than Lyndon.
You care too much about what other people say. The fact that Bernie supporters are so diverse can only be a good thing.
