Call it what you want. About 1.1% of the US population is a member of the Islamic cult. Noting that small number of people show up in circle of terrorists is noteworthy just as others note that majority of mass murders are non-white, most murders are male, etc. Read more into it if you want, but bigotry and bias are wrong. If you point out a killer is person of color, shall we presume you are racist because you noted it?
Well the kid you reference didn’t kill anybody. He did nothing wrong. He just happened to be an acquaintance of a mass murderer, and you of course obsess on the fact that he might be a Muslim. Yes, that makes you a bigot
About 2% of this country are homosexual, yet their control over the culture, language, schools, media, business, and such is overwhelming.
