Yes, you've got me, I'm against diversity and my tactic is to point out that conceptions of gender and race are fluid and personal, and to point out that James might be unknowingly labeling people and that labeling people can be hurtful.

I'm not a crowd - I wrote both of the anonymous comments above, and while my examples were explicitly described as scenarios to imagine, I thought of them because of the pain I've experienced in similar situations, in which someone else has labeled me and made assumptions about who I can represent, instead of waiting until they know me, and until I choose to let them know who I think I'm representative of, and who I'm really not, despite appearances and superficialities.
