I can see you're upset, but genuinely, I think it leads to a better community on lemmy in general to approach with good faith.
The point overall being, if you are asking in earnest, and are hoping for answers about what possible way forward we have, I would hope that you recognize that there are better ways to communicate that. I'm sorry it's upsetting that certain langue is interpreted differently, even if the core is the same, but it's the reality.
Given that reality, being upfront about your worries and feelings of helplessness is valid and helps to connect rather than dismiss. With that, expressing the lack of knowledge as a personal aspect, rather than framing the exhausting of options you're aware of as the end of all options, would help show that you are looking for whatever is next.
As for 'an answer', it's not something I can easily give because these are complex issues. The reality is it can't be distilled down to "Get out and vote" because the problems extend beyond that, and any real answer that match that simplicity would along the lines of "organize" but I assume like me, you'd find that sort of broad advice hollow.
I can't say what you should do because it depends on your local politics, what you're able to commit, where your politics sit, and ultimately what you think your place would be in whatever is done. With that I recommend black radical thought because I find it best encompasses the tools needed to learn for the reasons I mentioned. Along side learning, I think reaching out to local political groups for work that can be done would be a great way to see what options and opportunists marginalized folks are making for themselves.
In short, if you fear for the well-being of, black/brown, indigenous, immigrant, queer, or everyone else that will suffer under the coming wave of fascism, do as Mr Rogers says and look for the helpers, and if you can, help them.
