The supervisor's presence militated against a relaxed atmosphere.
She felt that she had spoken as impressively as it was necessary to do, and that in using the superior word "militate" she had thrown a noble drapery over a mass of particulars which were still evident enough.
This seemed to militate against life; and then I felt, for the first time and not the last, that death at least is straightforward.

- lessen or to try to lessen the seriousness or extent of
Examples
For all the abuse, there are moments of unmitigated delight as well.
