i think it depends on who you are and what you're willing to receive. it's like if you're not open to discussion, than yeah your viewpoint is limited. same thing with education within institutions b/c you can obtain education outside of 4 walls and an orator, if you're interested in learning and (perhaps i should've said this earlier) you attend an institution that has professors that foster critical thinking and independent thought, than education can be a form of activism. i think there are some institutions that do exist though that aren't on this tip and for those types, i'd agree with your opinion re: education not leading you to activism.
