In many cases, you can take a view (and craft an argument) that a particular action is one or the other, depending on whether or not you agree with it.

Take admission standards for colleges. Some colleges (at least as I understand it) are requiring higher SAT scores for Asians than other groups to consider students to be equally likely to be admitted. If you agree that’s good policy, you’re likely to argue that this represents increasing access to higher education for underrepresented non-Asian groups and therefore is an equality of opportunity measure. If you oppose it, you argue that those SAT scores represent a measure of the students’ demonstrated scholastic ability (an outcome at that point in time) and that perturbing those results is being done in an attempt to equalize these outcomes. (The truth is that it’s almost surely a mix of both.)
