Why should we iranians not hate arabs?

I don't hate arabs I hate their culture. Cyrus the great mad human rights and Islam messed it up .In Iran I know many christian arab friends who hate Islam more than us .And its a war people die , we killed arab men and they killed ours . And not like it was your rug or you fought the war . But I really hated that people backed down in tazahorat :(
