Oh, well if that's what you're worried about-- do some videos speaking out against that sort of thing. Problem solved.
Exactly! Rational debate is a very precious thing which is very important for a progressive society, in my opinion. These people who are criticising you for it don't place value on it one bit! They think that if it could possibly contribute towards race hate then might as well do away with it.
You know that that would be throwing the baby out with the bathwater, so to speak.
In my opinion, you already make it clear enough that you are against racial hatred and things like that. But if it is concerning you, just make it a bit more clear, like have your own signature paragraph at the end of each video where you condemn usage of your videos for incitement of racial hatred. I think you already have down that for some of your videos but not all.
Saying it could contribute to racial hatred so might as well do away with it is like culling a small pen of chickens with suspected bird flu by carpet bombing the whole farm, cuz you know, it might have spread into the rest of the farm.
