Sometimes, lending one's voice is literally all someone with disabilities can do. It can be disheartening to hear reinforced messages about how you're not doing/being enough or only doing the bare minimum when you're trying your hardest to show up for the larger community. Just because you can't see how we're contributing doesn't mean it isn't happening or isn't valuable. We are not a lazy demographic.
Right now, I'm not strong enough to march or attend rallies or sit-ins. I am currently in a place to be able to make modest donations, but this is certainly not always the case. The internet gives my disabled voice a potentially powerful platform that it wouldn't have otherwise. I'm going to use it when it's a viable option.
