You'll notice it's about how it makes the poster feel.

Complaints against the right are usually about their actions, the terrible consequences and how they hurt people.

Complaints against the left are often how it makes the complainer feel, it's a mental struggle to not admit they like the result of right wing policies and not being able to embrace a left wing position despite knowing on some level that they should.

Your reply proves me right.

>Caring about others and wanting a fair, even handed and democratic government is not self-righteous you muppet

It's self-righteous to say they care about other people but want to help those people with other people's money, not their own. Statistically speaking leftists give far less to charity.
