Milktoast

[Gregory]

1 - The absolute, unwilling and unfailing behavior to never [pick a side] on any issue, up to, and including, purposefully defending people, places, things and concepts from criticism from friends, colleagues, family, strangers and that one guy, even if said criticism is 100% warranted and valid.
2 - Cowardice [couched] as thoughtful [politeness].
3 - Bland to the point of being sickly.
