Long story short: tell your Congressfolk to protect gender-affirming care in appropriations bills, stop preventing prisoners and ex-prisoners from voting, and stop trying to destroy our CFPB. Use the tools in the upper right-hand corner of this page (or, if you're on a cellphone, the bottom of this page) to find your Congressfolk's phone numbers and/or use the email/petition tools in the following paragraphs.
The National Women's Law Center helps you tell your Congressfolk to protect gender-affirming care for our soldiers and their families. Transgender people exist, everywhere! At least half of America just needs to fucking get over it! At least half of America also needs remedial education in How Not to Be Cruel, but I'll try to avoid piling on and instead just say, like Rep. Casar of Texas, that transgender soldiers didn't deny your health insurance claim – your health insurance corporation did, and they did it with the help of those same Republican politicians who throw tantrums about taxpayer money going to trans soldiers. I might also add that taxpayer money pays for everything our government does. I hope that clarifies things for the benighted! But I won’t hold my breath.
The Vera Institute of Justice helps you tell your Congressfolk to ensure that folks in prison can vote. Tolerate no dick-thumping about how we always need to get tough on crime – rights are rights, and if everyone doesn't have them, then no one has them. Getting tough on crime doesn't mean taking voting rights away from criminals or making it harder for them to vote, either – getting tough on crime means making sure the real sociopaths can't hurt us anymore, which in practice means putting polluters and Medicare fraudsters and financial predators in jail. Besides which, if our government doesn't want us to vote, they'll just invent new crimes and put us all in jail! Hey, if I thought of it, you know theyhave. Especially TFG.
Finally, Civic Shout helps you tell your Congressfolk to keep their grubby mitts off our Consumer Financial Protection Bureau (or CFPB). Politicians have this hard-on for getting rid of a government agency that actually works on our behalf! How do I know they work on our behalf? Not just because they've returned billions of dollars to good Americans hurt by financial scams – but because Elon Musk says he wants to "delete" our CFPB (he's such a good little Cyberman!) because it's "duplicative." If it worked badly, he'd surely have said so! And not for nothing, but a Black President created this agency, and I'm pretty sure that's at the front of right-wingers' minds (including that of the apartheid diamond mine heir!) when they say they hate our CFPB.
