The racism is in the “they’re all the same” kind of thinking that picks up the negative behaviours of some and accuses an entire group of people who just happen to share the same etnicity/religion of being all like that.
It’s exactly the same when some Israeli soldier shots and murders a kid throwing stones at the armored buldozer razing his home, some israelis come out to defend his actions and then some racist says that “all jews support the murdering of children” using that as an example.
If your “argument” is anchored in an “their all the same” assumption, then you’re a racist.
