<human>: Give me a shortened version of the text

First, I am not racist. My brother and sister are lebanese, and I am métis. The rest of my family is mixed of various races as well. At my school the largest single cultural group is either white people or Lebanese people. The lebs only really hang out with each other, and they encourage each other to be typical "swag bro YOLO Gucci all day" kids who try and fight anyone who isn't lebanese. I'm not exaggerating either, this group commits hate crimes on a regular basis. I've met maybe 4 lebanese kids at this school who didn't look down upon white people. 

In class, we had a guest speaker doing a presentation on sexual health. We were discussing equality, and discrimination some groups (namely LGBT) have faced. I got picked to give an example of discrimination I had seen, and I said (as close to original as I can remember) "High schoolers usually aren't very tolerant towards gay people. I've noticed that the lebanese culture here really perpetuates that, there's a lot of discrimination towards gays." Immediately every leb kid in the class flares up "wallah I'll kick your ass for saying that" "wow are you racist you piece of shit" and so on. I was trying to say it the same way someone would say "the largest group who commits white collar crimes is old white men." 

I'm not really sure what to do. I'm not afraid of getting jumped or anything and I couldn't care less if the lebs at school hate me. I just don't want them to hate me because they misunderstood something I said. By the way, I don't know anybody in this class.
<bot>: Said remark in class that could be seen as somewhat racist. How do I make sure people don't have the wrong opinion of me and think I'm a bigot? I don't talk to anyone in class btw.
