Try your best, mate. People who are being negative are being that way for attention, unless a legit reason like offensive bus. and whatnot. But if they start telling you to f*ck off, don't do it. You're trying to make the world a better place, and so far, it's working. And for the people who DON'T change; The people who WE can't change, end up changing US. That means that at some point, they may switch sides, and change the way you look at things.
And always be yourself. Stay curious, stay weird, stay kind, and don't let anyone ever tell you you aren't smart or brave or worthy enough. And if they do tell you those things, we've got your back
