>>25277Anon, Comics and manga are separated because the way they developed is massively different and impacted by the cultures of America and Japan. While they have common roots, they are different things.
As to where
There are plenty of /co/ threads on
>>>/hobby/>>>/hobby/1328>>>/hobby/15233 (the old thread)
Also Western animation and capeshit threads too.
I frequent both there and here, but /anime/ was formed because people WANTED there to be separation.
