A gym membership is cheaper than an apartment, and will allow you access to restrooms and showers. If a public pool is cheaper, even better.
Familiarize yourself with food banks and other resources now, because access to both transit and the Internet is going to get a lot more tenuous.
Find a storage option for anything you truly value, even if it's just renting a lockable closet somewhere.
Try to find a housesitting gig if you can, which will give you shelter and maybe even income. Do not reveal your financial situation to your new employers.
I was only homeless for a few months, thank God, and like you I knew it was coming and had time to prepare. Some of the above is things I've done and some is things I learned later or wished Zid done. It took me a lot longer to climb out of that hole than to fall into it, but with hard work and luck and a lot of help I made it. I hope you can, too.
It does cost money to find and prosecute the offenders. Plus many crimes don't have a specific victim, but pose risks or harms towards society in general.
I can speak to this, as I was a mod of r/AskConservatives when reddit admin sent out the communiqué that misgendering someone or othrwise denying trans identity was a reddit rule 1 ("remember the human") violation. Which I think was a step in the right direction, but those first few months were... rough. Inconsistent communication from admin, inconsistent removals by admin, and a slew of bad-faith actions from users on both the right and the left. A lot of bans given out, the head mod resigned over it, another mod was permabanned from reddit over it, and the rest of us just decided the only safe course for all our users –querants and respondents alike– was to preclude any questions touching on trans identity. (Which was unpopular with every stripe, the hallmark of a good compromise.)
Admin was already getting better at enforcing this interpretation of Rule 1 by the time I resigned my modship over the API debacle. I can only imagine they've continued to become more consistent in the time since and gradually transphobes are being weeded out with sitewide bans, or at least getting the message and keeping their bigotry to themselves. I still think it would've been better from the start to address the matter face-on, rather than shuffling it in with the proscription other dehumanizing behavior, but reddit isn't know for great decision-making or forthrightness, is it?
You spread it on the bread, then flip it onto the PB.
