Age-restricted content

Sometimes content doesn’t violate our Community Guidelines, but it may be incompatible with YouTube’s Terms of Service or not appropriate for viewers under 18. In these cases, we may place an age-restriction on the video. This policy applies to videos, video descriptions, custom thumbnails, live streams, and any other YouTube product or feature.

You think I’m authoritarian? You could not be more incorrect if you tried lol. I think parents should be more responsible for the content their kids consume and what they do - but I also believe that age restrictions on content should exist to prevent access when even the best of parents can’t be there to stop it. I’m one of the few people on Lemmy who actually argues FOR free speech and less censorship lol
