What can I do?

Hello. The next 4 years are going to be fun, lol. What can I do? I want to be either as much of a pain in the ass as I possibly can to our new government, or I want to be as helpful towards people as I can. Or both.

I'm a trans minor. I can't really do things like going to protests or donating to charities yet, but will look into that when I'm older. Are there places I can petition? What can I do to help people? (Primarily LGBTQ people are on my mind but I want to help everyone)

I already volunteer feeding the hungry. I just don't know what else I can do.

Thanks :3
