Unfortunately it’s against the instance and lemmy’s rules to use your full range of expression if that includes name calling or swearing to insult someone.

We will exclude you from interaction if you insult, demean or harass anyone. That is not welcome behavior.

Please be kind and courteous. There’s no need to be mean or rude.

Exercise consideration and respect in your speech and actions.

Personal insults, particularly those related to gender, sexual orientation, race, religion, or disability [are considered unacceptable behaviour]
