Based on what did you draw such conclusions? Offend without any justification - a sign of marginality, a person of low level of development.
Because you came into a thread where people are grieving for a disaster that is continuing - will continue yet for months - and has uncounted cost in life, both animal and human. Yes, we know how many humans have died, but how many more will suffer? How many will suffer health affects from the smoke, the heat; how many of the brave firefighters will suffer long-term consequences of continuing the fight, day after day, until they are beyond exhaustion? And you came in here with your faux-moral superiority and your know-it-all attitude to tell us we should not mourn and grieve? How you dare!
Do I need to explain that large forest fires are a commonplace thing that only in the last million years in Australia there were tens, even hundreds of thousands?
Oh, god, you're one of those. Yes, Australia catches fire a lot. Occupational hazard, one might say. But not like this. Never before like this. Never before on this scale with this much devastation. Never before for such a prolonged period. Never before to the point that the only thing that will save us is the rain that probably will not come until April.
If you're here to argue some faux-moral superiority garbage, you can just get out until you learn some empathy - and that may be a long wait for all.
