The twitter account is that of an Arab girl saying what is noted in literature, which provides reliability for that literature and strengthens the assertion that Arabs are anti-black. So, combiningg literature and anecdotes, Arabs are some part anti-black. One doesn't have to "know every" single cac or Arab to know they have anti-black aspersions like one does not have to know every pedophile to know they are a danger to children. Your argument is like saying, "How can we know all Nazis hate Jews if we haven't met all Nazis?". In essence, you're a dumb fakkit.
As respects cacs, they have anti-black feelings and generally throw disdain on blacks. I don't have to fukking know every fukking cac to know that. I have history, literature, anecdote and research, same as Arabs. Read a book and stop questioning your betters.
Muslims are anti-black, so are cacs and Hispanics. Keep caping, dumb fakkit.
