That is definitely one of the issues with any social platform or outlet. There is always the push to form in and out groups based on unifying characteristics, behaviors, social status, etc. I do think a major thing that is missed is calling out behaviors and beliefs that are not supported by facts; e.g. giving the same weight of truth or spotlight to outlandish conspiracy theories vs. scientifically backed data (climate change is a good example)
Hopefully this place can find a happy medium that invites good faith discussion instead of bad faith actors.
If you are visiting YT on mobile, ReVanced has been working perfectly for me on Android. I’m not sure if there is cross-platform support, but there are alternatives to traditional adblockers out there.
