The inequality of equality arguments

Why do socialists fervently believe in only one type of equality? Why is it they only take any notice of eqaulity of outcome? There are two types of equality.

As long as governments ensure equality of opportunity for all, the equality of outcome is irrelevant. People are responsible for the outcome of their actions, not the government.

Nobody in this country goes without healthcare, shelter or food for free
