Someone Frames Me Of Saying Offensive Terms Online, Lies

I catch someone pretending to me on Discord, trying to copy by Discord ID, username, and description, to make it look like I said the f word towards anyone who happens to be LGBT. Since two of the cyberbullies are LGBT, the impersonator tried to make it look like I said offensive slur at them, whihc I never said at them.
The cyberbullies have said racist terms at me, which they should be held accountable for being racist to Asians.
