What's your idea of a smart responsible adult then? Is it continuing to push on a red herring after being called out thrice? Putting words into someone's mouth instead of honestly engaging with what's being actually said? Attacking your opponent for someone else's actions out of desperation? Throwing a tantrum and resorting to crude insults when challenged? All of this just to defend a white suprematist? Sheesh.
By all means keep doing what you're doing. Just don't act surprised when people don't look up to you and take your words with respect.
