I didn’t call them an asshole, I said they were behaving like one. I assume they’re perfectly capable of not acting that way and are just taking an opportunity where they feel they can get away with it.
The insult was in implying that what I say has no value simply because I’m pointing out the police aren’t the only ones who did things wrong here; rather than engaging and arguing ideas they made an ad hominem attack. Saying that in reply to me but directed at everyone else is incredibly rude.
