Sometimes certain demographics exhibit the same traits over and over again especially if they have exhibited the same unique traits for a significant duration of time.. Most often we notice the negative ones because they affect us directly. Traits like viiolence, criminal behavior, gang behavior, etc...and we regard them as a demographic with undesirable traits. Are we being racist.? No we’re being observant.
No, you’re being racist. Those elements are cultural and learned.
But perhaps you know better than Jesus??
