I dig Invidious. I think it's a great solution for people that want to interact with YouTube and not get bombarded with non-sense.
However in this day and age, you have to make a stand against hate speech. You can't just hope it goes away or it deals with itself, b/cit won't. We see what happens when we give it space.
And let's be real. The only time the free speech argument is deployed is when it is in defense of hateful and violent bigots.
This is how hate spreads. When people do nothing.
