First off...you're probably not going to get kicked off campus. You should deny everything, and refuse to answer any questions or talk to anyone. Also, if you haven't already. Delete facebook and never touch it again. Unsubscribe from their Jewy emails and never allow yourself to be linked back to the site as they will attempt to get you to log back in which renews your account. Delete all of your social media accounts that have anything to do with you personally...and lay low. If you get kicked out fuckem. There are other places to go to school.
There are dudes on here who will hate on me for recommending this but join a frat. It helps to have 80-100 brothers that are there to back you up and who have influence on campus. They are pretty much the only part of campus life left that is implictly (and many times explicitly) White.
