I say this as someone who adamantly supports the 2nd amendment.
If you are a young black male you should probably not open carry as you are inviting your own economic ruin and bodily harm.
Since you are in college it probably means 1) you're young and dumb 2) your family has a little money so you've been insulated from how unfair this society really is when it comes to young black males.
Police Officers don't mind middle aged white males open carrying so much. However, when it comes to young black males, they'd love to get your mugshot and prints into their system on some trumped up charges. After that, they will pull you over, frisk you, harass you for the rest of your life.
They will give you a criminal record that will economically cripple you for the rest of your life.
As a young black male you are already economically crippled for life. Don't be stupid and compound your problems. In this economic environment, you cannot afford to have a criminal record when applying for a job, any job.
Someday you will have kids. They will pay the price in diminished futures because of your stupidity. Don't listen to anything these middle aged white males who post here tell you. Their understanding of modern day racism is infantile. They don't know because they don't need to know and, possibly, don't want to know.
