Why do leftists have a hard time admitting it when they are wrong in a argument?

Arguing leftists usually ends one of the following the 3 ways if you prove them wrong:

1. They try to deflect or move the goalpost

2. They calls you slurs or demeaning names and says you are not worth arguing with and then stop arguing there and may block you

3. They just stop arguing and shut up and keep being wrong elsewhere

Why don’t they try for example admitting you are right when you own them in a argument?
