Pejorative word allowed through Wikipedia

"(pejorative designation)"
 

 I tried to modify it in romanian language. Translation below.

"Dallas word doesen't exist as a designation of a neighborhood. Is a pejorative word."

"(pejorative designation, a small village next to Bahlui river)."

A automatic account was made for me.

A temporary account.

 PatrocleBot had canceled the words.

"Doesen't seem to be constructive and was canceled."
 

"Dallas (small village next to Bahlui river)"

 So, i'm not allowed to modify it.

Bots are made by humans. This bot cannot make the difference between AI and reality. 

What is than the purpose of Wikipedia, to be 100 % free speech ?
