You do realize what you said in chat was 100% not appropriate?
That topic is really triggering, and it was insensitive to stay something about the topic that you did in chat. You were banned instantly because of how you said it and the causality of it, usually I would not ban someone because of it and instead clear chat and warn. But you took it too far.
I'll give you another chance, ban will be reduced to 1 week instead.
If this behavior happens again you will be permanently banned.
