Aw, lots of people in ST were racist, or specie-ist.
How many times does someone remark "Typical Klingon, always yadda yadda yadda" or "That would be the Romulan way of..." or "Leave it to the Ferengi to..." or "Only a Vulcan would do something something".
No one seems to mind generalizing entire races. But use that same language when talking about Irish or Japanese or Jews or Africans or French or Hindus or any other human group...
Would it be "specie-ist" to say something like:
- Typical squirrel, always gathering nuts and burying them!
- Has anyone seen my rat collection? That snake better not have eaten them alive again!
- Damn that cold virus! Always making people sick!
