I voted "no", not because there is no evidence that people grant privilege (making untrue assumptions in order to give unearned advantage to individuals). Rather, I see these kinds of questions as making assumptions about outcomes in order to advocate universal fixes to restructure the social world.
Relationships are complex, not simple 1 demential. Muslims may not be given housing as easily as christians (for example) because they are not "us", whatever "us" means in the context. Thats a universal behaviour. blacks prefer blacks, Pakistani's prefer Pakistani's, feminists prefer feminists, and Leafs fans (if there are any) prefer Leafs fans. The reasons are also complex and deeply engrained in us because of our "self-preservation", genetic leanings. We make many unconscious and some conscious judgements about levels of safety and desirability in every moment not only about people but our environment as a whole.
Additionally, simply because there's a preference does not mean outsiders are never given access. Each identity group has a barrieier for entry to outsiders. So pointing at 8 or 9 underprivileged groupings is very inaccurate, IMHO.
So my vote was less about the question and more about the assumptions, which are admittedly difficult to sort through. in this kind of poll.
