I don't really have time for a full lecture but:
1. despite being marketed to children the furry fandom has a lot of nsfw and many parts of it are inherently sexual
2. the furry fandom has high rates of pedophilia and zoophilia
3. many furries are quite hypocritical and literally defended sexualised stuff and nsfw during the burned fur incident in the 1990s
for more info read HaloGuy7's anti furry docs, and actually read it don't just skim and claim it's not researched or a mindless rant because it is actually quite well researched and structured
