I'm going to purposely misspell peoples' names
Why are you deciding to misspell other people's names?
I have no respect for ignorant people
Regardless of what you think of the other person, there's no reason you should do that.  It's disrespectful to offend people on purpose by doing things like that.
I'm very disrespectful to the ignorant people.
If you do things to disrespect other people, they will find it difficult to respect you. It's better to intentionally be a good person and help people.
