All the time. Especially in the wake of Columbine and for years afterwards. I was a quiet nerdy kid in junior high school (Columbine happened when I was in 6th grade), and people started becoming wary of me after that, probably because I didn't share every detail of my personal life with the whole school. I partially brought it upon myself once I turned 14 and decided my new favorite color was black. People were terrified of me, I guess because I was quiet and "dark" and sort of a watcher, but they covered that fear trying to crush my self-esteem into a bloody pile on the ground. It scared them even more when I bit back, which put up their defenses even more. I live in a small town where difference, instead of welcomed with loving arms, is resented. I knew that by dressing like that, I was probably only making things worse for myself, but I got a thrill out of knowing they feared me. That power was so exhilirating. Not to mention, I've always thought the old Victorian vampire Gothic style was beautiful, I liked the way I dressed, and I wasn't going to change that because it wasn't "acceptable." That being said, Klebold and Harris were severely psychotic and while bullying may have pushed them to the edge, only a severe mental illness would silence their logic and consciences. I had a lot of friends who were enraged in high school, they'd talk about how they thought about just offing everyone, but they had one thing Dylan and Eric did not, a conscience. Judging by the transcript, they had a few specific targets, but after that it was just whoever was in the bullets' paths. Revenge may have been a motive, but it wasn't the real reason they did it. They did it because they were psychopaths. Sadly enough, their deaths may have been the best thing for this world, they were extreme dangers to themselves and others, as they soon proved. I think people will always be searching for "why" they did it. I can only imagine there was a plethora of justificiation in their minds, that only they would or could ever understand.
