Shitty liberal culture tells us to be blind to differences amongst people, and stupid romance myths tell us love is blind. But for folks who have radical politics, and recognize that identity is a major vector of privilege and oppression, we know that love and sex and culture are not blind to difference, but rather that difference play a major role in sex and romance and family structure. We also understand that experiencing and acknowledging the identities we live in and are perceived in is important, and finding community with other people who are like us can be empowering and healing.
The standard liberal motto – that it is sometimes necessary to resort to violence, but it is never legitimate – is not sufficient. From the radical-emancipatory perspective, one should turn it around: for the oppressed, violence is always legitimate – since their very status is the result of violence – but never necessary: it is always a matter of strategic consideration whether to use force against the enemy or not.
