Open Forum: How Inclusive Should 'Queer' Be?

The term queer has been evolving rapidly as of late, and has become an inclusive term of more identities, some people consider this positive, others confusing and unnecessary. In your mind is queer just an umbrella term for sexual and gender minorities or does it stretch beyond that? Is queer radical and political in the sense that anything non hetero-normative can be described as queer? Could a straight couple consider themselves queer, or is it impossible for them to be considered non-hetero normative? Are people who practice BDSM and kink, queer in the sense that they engage in alternative sexuality or is the term limited for those with sexual preferences as opposed to sexual orientation? What are the social and political connotations of limiting or extending the definition of queer identity?
