Old Friends

This might trigger some people. But anyone else have like those old friends who are on your fb but you never talk anymore and they keep putting annoying posts about their opinions? I have this one friend from high school and she keeps posting like political views and extreme feminist stuff (and yes I'm a feminist but I'm not about that men are all out to get us extremeist stuff). It's annoying as hell but I feel bad deleting her. It's kind of like damn someone went crazy after high school.
