Here here. I'm not a doomer and frankly can't stand that mindset. As far as we're concerned there will always be people on this planet and we should do whatever we can to give them an existence that allows for more than just survival. I have some hot takes on doomers:

1. Being a doomer is a very privileged position to have. A doomer appears to absolve themself of having a stake in the future, and therefore they don't really need to take action. If they did, their actions would only serve to discomfort them today and wouldn't have an impact on those living in the future, so why should they bother? They usually hide this position behind "I'm just being realistic" or "I'm just working with the data I have." Frankly they're the worst, as they'll argue with people to justify their shitty attitude and pull people down in the process.

2. being a doomer is some sort of type-A or perfectionist personality issue. Since the future won't be perfect, they can't participate in mitigation since things won't turn out "perfect".

3. being a doomer is related to an anxiety problem. When I'm anxious about something, I can't see past the theoretical event I'm anxious about. Therefore I can't think about possible outcomes or solutions and can only fixate on the terrible event.

4. They're just young and haven't seriously invested in the future yet. However they don't see why they should when there's a bunch of doomers saying the end is certain.

5. They're old and regret the life they lived and choices they've made, thus they take comfort in the idea that there won't be a worthwhile future. Therefore their regretful decisions were in fact the best decisions they could have made. Imagine how comforting a future societal collapse would be to a boomer who regrets not having a family. They'd probably be relieved.

Again, these are hot takes from some person on the internet. However if one hits a nerve you may want to exercise some introspection and maybe try helping out instead of discouraging people from trying.
